Hey there, let's work through this problem where your local Git commands (init, add, commit) work fine, but pushing to GitHub hangs with no response after a system restart. Here are the most likely fixes, ordered by how common they are:

1. Verify Remote Repository Configuration #

First, double-check that your remote URL is correct and pointing to the right GitHub repo. Run this command in GitBash:

git remote -v

Look for the origin entry—make sure it's either a valid SSH URL (git@github.com:your-username/your-repo.git) or HTTPS URL (https://github.com/your-username/your-repo.git). If it's misspelled, update it with:

git remote set-url origin <correct-url>

2. Troubleshoot SSH Connection (If Using SSH) #

If you use SSH to connect to GitHub, a system restart might have killed your SSH agent or unloaded your private key. Let's test the connection first:

ssh -T git@github.com

If this hangs or throws an error, try these steps:

• Start the SSH agent manually:

  eval $(ssh-agent -s)
  

• Add your private key to the agent (replace id_rsa with your key filename if different):

  ssh-add ~/.ssh/id_rsa
  

• Also, check if your firewall or antivirus software is blocking SSH traffic—sometimes restarting the system resets these rules, so temporarily disable them to test.

3. Fix HTTPS Authentication Issues (If Using HTTPS) #

For HTTPS connections, the credential cache might have been cleared or corrupted after the restart. Try these fixes:

• First, try manually triggering a credential prompt by clearing the cached credentials:

  git credential-manager-core erase
  

  Then run git push origin master again—you should be prompted to enter your GitHub username and personal access token (note: passwords are no longer supported for GitHub HTTPS, so use a PAT if you haven't already).
• Check your Git credential helper setting to ensure it's configured correctly:

  git config --global credential.helper
  

  If it's set to something unexpected, reset it to the default for Windows:

  git config --global credential.helper manager-core
  

4. Check Network Proxy Settings #

A system restart might have enabled or changed a proxy setting that's interfering with Git. Verify your Git proxy config:

git config --global --get http.proxy
git config --global --get https.proxy

If you see proxy URLs that you don't need, remove them:

git config --global --unset http.proxy
git config --global --unset https.proxy

Also, check your system-wide proxy settings (Windows Settings > Network & Internet > Proxy) to make sure no unexpected proxies are enabled.

5. Reset GitBash and Update Git #

Sometimes GitBash's network components can glitch after a restart. Try these quick fixes:

• Close and re-open GitBash (preferably with administrator privileges).
• Update Git to the latest version to rule out any bugs in older releases:

  git update-git-for-windows
  

6. Test Other Remote Operations #

To narrow down the issue, try running git fetch origin or git pull origin master. If these also hang, the problem is definitely with your network/connection to GitHub. If they work but push still hangs, check your GitHub repo settings to ensure you still have push permissions (though this is less likely if everything worked before the restart).

Start with the SSH/HTTPS connection test first—those are the most common causes after a system reboot. Let me know which step resolves your issue!
