What does this error mean? #

The error Push failed: Failed with error: unable to access https://github.com/MY_PROJECT_NAME: SSL certificate problem: self signed certificate in certificate chain pops up when Git tries to establish an HTTPS connection with GitHub, but hits a self-signed certificate in the SSL verification chain. This nearly always stems from a corporate proxy, local VPN, or network security tool that intercepts HTTPS traffic and replaces GitHub's official certificate with its own unrecognized self-signed one. Git doesn't trust these unvetted certificates by default, so it blocks the push to keep your connection secure.

Solutions I've tested (and seen work for other devs) #

Here are three solid fixes, ordered from most secure to quick-and-dirty:

1. Import the self-signed certificate into Git (Recommended)

   • First, grab the certificate from your network tool/proxy:
     • Open Chrome/Firefox, visit https://github.com, click the lock icon in the address bar → "Certificate" → "Details" tab → "Copy to File". Pick the Base64-encoded X.509 (.CER) format and save it somewhere easy to find.
   • Tell Git to trust this certificate:
     • Open Android Studio's Terminal tab, run this command (replace the path with your saved certificate's location):

       git config --global http.sslCAInfo "/absolute/path/to/your/certificate.cer"
       

     • If you only want this fix for the current project, remove the --global flag.

2. Switch to SSH for GitHub authentication
   This bypasses HTTPS entirely, so SSL certificate issues vanish:

   • Generate an SSH key on your machine (search "generate SSH key for GitHub" for step-by-step if you haven't done this before).
   • Add the public key to your GitHub account under Settings → SSH and GPG keys.
   • In Android Studio, go to File → Settings → Version Control → Git and confirm the SSH executable is set to "Native".
   • Update your project's remote URL: Go to Git → Manage Remotes, edit the existing remote to use the SSH format: git@github.com:YOUR_USERNAME/MY_PROJECT_NAME.git

3. Temporarily disable SSL verification (Not recommended long-term)
   If you need a quick test fix, you can turn off Git's SSL check. Note this is insecure because it lets Git trust any certificate:

   • Run in Android Studio's Terminal:

     # Applies to all Git projects on your machine
     git config --global http.sslVerify false
     
     # Or only for this specific project
     git config http.sslVerify false
