But before we discuss those methods, it would be better to understand what precisely the SSL Certificate Problem: Unable to get Local Issuer Certificate error is and what causes it.

What is the SSL Certificate Problem: Unable to get Local Issuer Certificate Error?

The SSL Certificate Problem: Unable to get Local Issuer Certificate error is a common issue that developers often encounter while using Git Bash, a Windows command line tool to push, pull, or clone a Git repository.

What Causes the Unable to Get Local Issuer Certificate Error?

The “Unable to Get Local Issuer Certificate” error stems from a misconfigured SSL certificate on your local machine. This misconfiguration prevents a successful HTTPS handshake from taking place.

The error is often linked to self-signed or corporate certificates, particularly with Git. (Self-signed certificates are mainly used in testing or development environments and are not verified by trusted Certificate Authorities. Git may throw an error when encountering such certificates.

Corporate organizations often have their own Certificate Authorities, but these certificates may not be trusted by external services like Git, leading to the same error.) Visual Studio Code users may encounter it due to a misconfigured certificate path on their machine.

3. Open ca-bundle.crt file.
4. Paste the Git SSL certificate at the end of the .crt file.
5. Save the file.

Method 3: Reinstall Git & Select SSL Transport Backend Option

If facing trouble in running Git commands like – git pull, push, or clone, reinstall Git and select the SSL Transport Backend option. Follow the steps mentioned below to accomplish the same:

• Uninstall Git by using the Control Panel.
• Once the uninstallation process is complete, perform these actions:
  • Open a web browser (Google Chrome).In the URL bar, type https://git-scm.com/download/win and press Enter.
  • Download the appropriate Git version.
• During the installation process, select the SSL Transport Backend option.

Method 4: Grant Repository Access to SSL Certificates or Reassign Path in VS Code

If the Unable to get Local Issuer Certificate error occurs inside VSC, perform the below-mentioned steps to resolve it:

• Reconfigure Git with the –global flag on your SSL certificate configuration by running the git config –global http.sslBackend schannel command in the terminal.
• If the error is due to accessibility, set the accessibility at the system level by opening the terminal with administrative privileges and running the git config –system http.sslBackend schannel command.
• If the error is due to location misconfiguration, use the git config –global http.sslcainfo “Path” command to reassign the path.
