We appreciate that! Most people who use the Internet recommend its attractive user interface. When using the Google Chrome browser for viewing SSL-secure websites, you might often see the SSL privacy issue &#8220;<strong>ERR_SSL_PROTOCOL_ERROR<\/strong>.&#8221; <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Subsequently, this problem frequently goes away by itself when you reload the website, but at times it shows up again.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This Error is irritating and disturbing, and is one of the most common errors you could encounter when exploring the Internet, whether on a Chrome or Android device. The <a href=\"https:\/\/certera.com\/blog\/what-is-ssl-tls-https\/\">SSL protocol<\/a>, used to encrypt data between a website and your Browser, frequently has issues that lead to this Error.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It also indicates that the website you are attempting to view is not secure and that your Browser cannot create a secure connection. There are several causes for this issue. However, you may address each one with simple solutions. Let&#8217;s explore!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-an-ssl-protocol-error\">What is an SSL PROTOCOL ERROR?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The ERR_SSL_PROTOCOL_ERROR, also known as This site can\u2019t provide a secure connection error or <a href=\"https:\/\/certera.com\/kb\/how-to-fix-your-connection-is-not-private-on-windows-and-mac\/\">Your connection is not private<\/a>&#8221; . It occurs when a website has SSL certificate issues or problems with the HTTPS protocol. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Numerous causes, such as an outdated browser or OS (Operating System), an <a href=\"https:\/\/certera.com\/kb\/how-to-fix-the-neterr-cert-date-invalid-error\/\">invalid SSL certificate<\/a>, or an improper SSL setup on the server side, may cause this Error.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Suppose you continue to receive warnings of this type on your mobile or PC browser. In that case, we&#8217;ve provided several solutions for <strong>&#8220;fixing err ssl protocol error in Chrome<\/strong>&#8221; and &#8220;<strong>fixing err ssl protocol error on Android<\/strong>.&#8221;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-typical-reasons-for-the-err-ssl-protocol-error\">Typical Reasons for the ERR SSL PROTOCOL ERROR<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here are a few potential reasons why you are getting this error message.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Incompatible expansions from third parties<\/li>\n\n\n\n<li>Inadequate connections to the Internet<\/li>\n\n\n\n<li>Incorrect configuration&nbsp;of the proxy<\/li>\n\n\n\n<li>An out-of-date SSL\/TLS protocol version<\/li>\n\n\n\n<li>Inaccurate time and date<\/li>\n\n\n\n<li>Expired Certificate<\/li>\n\n\n\n<li>A mismatch between the encryption methods used by the client and server.<\/li>\n\n\n\n<li>An insecure SSL certificate also ends up displaying the SSL connection error message.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-workaround-for-net-err-ssl-protocol-error\">Workaround for net::ERR_SSL_PROTOCOL_ERROR<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Try the techniques below one by one:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-remove-your-ssl-state\">Remove\u00a0Your\u00a0SSL State<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If this warning continues disturbing you,\u00a0you can try <a href=\"https:\/\/certera.com\/kb\/how-to-clear-ssl-state-in-your-browser\/\">erasing your System&#8217;s SSL state<\/a>. T<strong>o achieve it, follow the instructions below:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Click on the <strong>Windows <\/strong>icon<\/li>\n\n\n\n<li>Type &#8220;<strong>Internet Options<\/strong>&#8220;, and a new Internet Properties view will appear<\/li>\n\n\n\n<li>Click on the <strong>Content Tab<\/strong><\/li>\n\n\n\n<li>In the <strong>Certificate <\/strong>section, click on &#8220;<strong>Clear SSL State<\/strong>&#8220;<\/li>\n\n\n\n<li>SSL State will be cleared in seconds.<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image is-style-twentytwentyone-border\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" width=\"408\" height=\"535\" src=\"https:\/\/certera.com\/blog\/wp-content\/uploads\/2023\/05\/clear-ssl-state.png\" alt=\"Clear SSL State\" class=\"wp-image-975\" style=\"width:306px;height:401px\" srcset=\"https:\/\/certera.com\/blog\/wp-content\/uploads\/2023\/05\/clear-ssl-state.png 408w, https:\/\/certera.com\/blog\/wp-content\/uploads\/2023\/05\/clear-ssl-state-229x300.png 229w\" sizes=\"(max-width: 408px) 100vw, 408px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">Now, proceed to reopen the web page with <strong>Chrome<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-check-your-system-s-date\">Check your\u00a0System&#8217;s Date<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The most common cause of SSL failures is the date. Your Chrome browser will display this error when the dates on your computer and the server you&#8217;re attempting to access are out of sync. Change your system&#8217;s date to the current date to rectify the issue, and then try reassessing the website. You won&#8217;t run across any problems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-delete-browsing-data\">Delete Browsing Data<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sometimes, browsing data may also get in the way of your internet browsing, causing you to get that annoying SSL error. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Follow the instructions below <\/strong>to remove browsing history from your Chrome browser if your computer&#8217;s date is accurate:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Ctrl + Shift + Delete<\/strong> when using <strong>Chrome<\/strong>.<\/li>\n\n\n\n<li>Ensure &#8220;<strong>All Time<\/strong>&#8221; is selected as the time range.<\/li>\n\n\n\n<li>&#8220;<strong>Cookies and other site data<\/strong>&#8221; should be checked in the checkbox.<\/li>\n\n\n\n<li>Check the &#8220;<strong>Cached images and files<\/strong>&#8221; checkbox.<\/li>\n\n\n\n<li>Click on <strong>Clear<\/strong> Data.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Please wait for it to finish, then attempt to reload the webpage in your Browser when it is completed. There is an excellent possibility that it will open without any issues.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-turn-off-antivirus-software-and-third-party-extensions-for-the-browser\">Turn off Antivirus Software and Third-Party Extensions for the Browser<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Extensions are a great approach to increasing the functionality of your browser. These extensions can often interfere with protocol settings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Visit your extensions page by selecting <strong>More Tools&gt; Extensions<\/strong> from the Chrome menu to see any possible extensions causing issues.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Turn off<\/strong> all your extensions. Then, go back to the webpage where the issue appeared. You may conclude that an extension is at fault if it disappears.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The next step is activating each extension and refreshing the page between each one. You can start looking for a solution when you&#8217;ve identified who the criminal is. Disabling any installed firewalls or antivirus programs is also a brilliant idea.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-turn-off-the-quic-protocol\">Turn off the QUIC Protocol<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Google first created a novel internet protocol called <strong>QUIC<\/strong> for its <strong>Chrome<\/strong> browser. It is a replacement for the <strong>HTTP protocol<\/strong> to enhance performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Also Read:<\/strong> <a href=\"https:\/\/certera.com\/kb\/how-to-resolve-the-err_http2_protocol_error\/\">How to Resolve the ERR_HTTP2_PROTOCOL_ERROR?<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most recent versions of Chrome have <strong>QUIC<\/strong> enabled by default, but you may turn it off from the options panel. Disabling <strong>QUIC <\/strong>will force the browser to use HTTP instead for those with connection issues.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>QUIC<\/strong> could be turned off in Chrome by entering <strong>chrome:\/\/flags\/#enable-quic:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Click the dropdown menu next to <strong>Experimental QUIC Protocol<\/strong><\/li>\n\n\n\n<li>Select <strong>Disabled<\/strong>.<\/li>\n\n\n\n<li>Click the <strong>Relaunch<\/strong> button, which is at the bottom of the page.<\/li>\n\n\n\n<li>Return to the website you are trying to load and check whether the protocol challenge is still there.<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image is-style-twentytwentyone-border\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" width=\"1024\" height=\"516\" src=\"https:\/\/certera.com\/blog\/wp-content\/uploads\/2023\/05\/disable-quic-protocol-in-chrome-1024x516.png\" alt=\"Disable QUIC Protocol in Chrome\" class=\"wp-image-980\" style=\"width:768px;height:387px\" srcset=\"https:\/\/certera.com\/blog\/wp-content\/uploads\/2023\/05\/disable-quic-protocol-in-chrome-1024x516.png 1024w, https:\/\/certera.com\/blog\/wp-content\/uploads\/2023\/05\/disable-quic-protocol-in-chrome-300x151.png 300w, https:\/\/certera.com\/blog\/wp-content\/uploads\/2023\/05\/disable-quic-protocol-in-chrome-768x387.png 768w, https:\/\/certera.com\/blog\/wp-content\/uploads\/2023\/05\/disable-quic-protocol-in-chrome.png 1525w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-verify-the-antivirus-settings\">Verify the Antivirus Settings<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sometimes, the source of an SSL problem may also be your antivirus software. All current antivirus software analyzes websites for potentially harmful\u00a0malware\u00a0and other security risks, which includes <a href=\"https:\/\/certera.com\/kb\/how-do-you-check-the-tls-version-of-your-website\/\">looking at a site&#8217;s SSL\/TLS version<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The antivirus prevents us from visiting a website if it is utilizing an <a href=\"https:\/\/certera.com\/blog\/ssl-tls-timeline-history-of-ssl-tls-protocol-versions\/\">out-of-date SSL version<\/a>. In this instance, the issue can be fixed by momentarily turning off the antivirus. Turn off your antivirus software to check if you can access the erroneous\u00a0website.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-enable-the-ssl-tls-versions\">Enable the\u00a0SSL\/TLS Versions<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Activating all SSL\/TLS versions is an additional strategy you could use. It will make sites using outdated or unsafe protocols load more slowly. Although not usually advised, this technique can assist you in locating the source.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Select System from the <strong>Advanced<\/strong> <strong>Settings<\/strong> menu in Chrome to enable all SSL\/TLS versions.<\/li>\n\n\n\n<li>Then choose <strong>Open Proxy settings<\/strong><\/li>\n\n\n\n<li>Click the <strong>Advanced<\/strong> tab:<\/li>\n\n\n\n<li>The boxes for each TLS\/SSL version should be clicked.<\/li>\n\n\n\n<li>Once you are done,&nbsp;refresh your browser to check if you can still access the page.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"407\" height=\"533\" src=\"https:\/\/certera.com\/blog\/wp-content\/uploads\/2023\/05\/interenet-security-setting.png\" alt=\"Internet Security Settings\" class=\"wp-image-3359\" srcset=\"https:\/\/certera.com\/blog\/wp-content\/uploads\/2023\/05\/interenet-security-setting.png 407w, https:\/\/certera.com\/blog\/wp-content\/uploads\/2023\/05\/interenet-security-setting-229x300.webp 229w\" sizes=\"(max-width: 407px) 100vw, 407px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-choose-the-level-of-your-internet-security-and-privacy\">Choose the Level of your Internet Security and Privacy<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Your access to specific websites can be restricted if your internet security and privacy settings are too extreme. <strong>You can alter your settings to see if it solves this Error.<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>To accomplish this, enter &#8220;<strong>Internet Options<\/strong>&#8221; into your device&#8217;s search bar and press Enter.<\/li>\n\n\n\n<li>Select the <strong>Security<\/strong> tab and use the slider to adjust it to the medium level in the Internet Properties window&nbsp;that shows up:<\/li>\n\n\n\n<li>Click the <strong>OK<\/strong> button once you&#8217;re done.<\/li>\n\n\n\n<li>Try visiting the website once more after refreshing your Browser.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-check-your-firewall\">Check your Firewall<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Chrome will be unable to access any websites that are included on your Internet Firewall&#8217;s block list. Verify your Firewall&#8217;s block list&nbsp;to make sure the website you&#8217;re attempting to access is not on there. Removing it will allow you to reload the webpage if you find it there.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-verify-your-ssl-certificate\">Verify Your SSL Certificate<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Checking your SSL certificate is another option if you still see an issue notice. As previously stated, a revoked, lost, or <a href=\"https:\/\/certera.com\/blog\/what-happens-when-ssl-certificate-expires\">expired certificate<\/a> could trigger the error message. Therefore, it&#8217;s crucial to ensure that the one you&#8217;re using is legitimate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can verify your certificate&#8217;s validity with an <a href=\"https:\/\/certera.com\/ssl-tools\/ssl-checker\">online SSL checker Tool<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-reaching-out-to-the-website-s-owner\">Reaching out to the Website&#8217;s Owner<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you go through all the&nbsp;previously mentioned steps but cannot access the website, there could be a server-side conflict. Inform the website owner regarding the issue; they might be able to resolve it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-make-use-of-a-vpn-to-access-the-website\">Make use of a VPN to access the Website<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If your internet provider or the site stops you from accessing the website, your browser could show various error messages. Nevertheless, you may still access the website using a virtual private network. To test whether you can access the website, switch your VPN&#8217;s default zone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here, an important note is to execute this process only if you have complete confidence that visiting the website you seek to access won&#8217;t result in legal action being taken against you by the authorities.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-conclusion\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It may be frustrating\u00a0to encounter error warnings when visiting a website. ERR SSL PROTOCOL ERROR is one of the most frequent ones you might come across. Fortunately, there are a few fixes you can use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Several factors can cause this mistake, as we covered in this article. The most probable perpetrators include wrong system or protocol settings, outdated or invalid certificates, and inappropriate cache settings. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You must be able to swiftly remediate this issue by deleting your cache, verifying the validity of your SSL certificate, and changing your protocol and privacy settings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We hope that this article will assist you in addressing the issue.
