GitHub Push Internal Server Error Fix Guide (November 2025)

If you encounter the GitHub Push Internal Server Error, this guide is for you. This GitHub error has left many users quite frustrated. To resolve the issue, follow these simple steps to troubleshoot the error instantly.

GitHub Push refers to the act of uploading committed changes from a local Git repository to a remote repository hosted on GitHub. This action is performed using the git push command. 

A GitHub push internal server error is a generic server-side issue. This means the problem likely lies with GitHub’s services, rather than your local configuration. 

Here are the troubleshooting steps you should follow:

Check GitHub System Status

  • First, verify if there is a known platform-wide issue. Server errors are often transient and may resolve on their own. 
  • Visit the official GitHub Status page to check for any current incidents or service degradations.
  • If an outage is reported, you may simply need to wait until GitHub resolves the issue and then try pushing again. 
  • If the status page shows all systems operational, the issue might be specific to your interaction with the repository.
  • Retry Push: The error could be a temporary network or server-side glitch.

Update Your Local Repository: 

  • Your local repository might be out of sync with the remote.
  • Ensure your local branch is up-to-date with the remote before pushing.
  • Run git pull origin <branch-name> to fetch and merge the latest changes, resolve any conflicts, and then try pushing again.

Check Credentials: 

  • Ensure your authentication credentials (Personal Access Token or SSH key) are correct and not expired.
  • GitHub does not accept account passwords for Git operations over HTTPS. You can manage your tokens and SSH keys in your GitHub account settings.
  • Ensure you have committed changes: You cannot push if you haven’t locally committed your changes first.

Verify Repository Existence and Permissions: 

Make sure the remote repository exists and that your account has write permissions to the branch you are pushing to. 

Large file push: 

  • Pushing a single large commit or many large files (especially with Git LFS) at once can occasionally trigger a server error.
  • Try increasing the Git buffer size: git config –global http.postBuffer 157286400.
  • Alternatively, break down large commits into smaller ones and push them individually.

Antivirus/Firewall: 

In rare cases, local security software might interfere with the connection.

  •  Add GitHub Push to your firewall exception list.
  • Type Firewall in the search bar.
  • Tap on the settings tab and open it.
  • Go to Allow an app through the firewall and select it. 
  • Tap on the Allow another app option.
  • Click on Browse and locate Add GitHub Push.
  • Select GitHub Push and add it to the list of apps allowed through the firewall.
  • Check if the error is fixed.

Contact Support: 

  • If you’ve exhausted all options and the issue remains specific to your repository.
  • The server may have an issue with specific content in your push, requiring intervention from GitHub Support.
  • Contact them and share the issue they will soon help troubleshoot the error. 

Hope the above solutions have helped fix the issue.
