What's Wrong?

Environment: Claude Code web (claude.ai/code)

Issue: Git push stopped working mid-project with persistent 403 errors,
despite the GitHub OAuth app being authorized. Previous commits on the
same branch pushed successfully.

Error:
remote: Permission to raymondckearney/Curio.git denied to raymondckearney.
fatal: unable to access 'http://127.0.0.1:/git/raymondckearney/Curio/':
The requested URL returned error: 403

Steps taken without success:

• Disconnected and reconnected GitHub in claude.ai settings multiple times
• Closed and reopened the session (proxy port changed, 403 persisted)
• Attempted push via GitHub MCP tool (same 403)

Root cause observed: GitHub settings show Claude is authorized as an OAuth
app but "has not been installed on any accounts" — the GitHub App
installation appears to be missing or was never completed, so only read
access works, not write/push.

Request: The Claude Code web onboarding flow should ensure the GitHub App
is fully installed (not just OAuth-authorized) before allowing git
operations, or provide a clear "Install GitHub App" button when push
access fails.

What Should Happen?

GitHub push should work reliably throughout a session. If the GitHub App installation is missing or the push token expires, Claude Code should detect this automatically and prompt the user to reinstall/reauthorize — not silently fail with a 403.

Error Messages/Logs

Steps to Reproduce

1. Connect GitHub via claude.ai settings (OAuth only — no GitHub App install prompt)
2. Open a Claude Code web session on an existing repository
3. Have Claude make and commit changes
4. Claude attempts git push → 403 error
5. Disconnecting/reconnecting GitHub in settings does not fix it
6. Closing and reopening the session does not fix it
7. Push remains broken for the remainder of the session

Having same issue...

Body:

Git push has stopped working for my repository (alteonsolutions/mapper-scripts) with a persistent 403 error. This was working correctly for weeks and stopped without any changes on my end.

Error:

remote: Permission to AlteonSolutions/mapper-scripts.git denied to AlteonSolutions.
fatal: unable to access 'http://127.0.0.1:[PORT]/git/AlteonSolutions/mapper-scripts/': The requested URL returned error: 403
What I've tried:

Disconnected and reconnected GitHub in Claude Code settings
Opened multiple new sessions
Tried pushing to both main and feature branches
Git fetch (read) works fine — only writes fail
Additional observations:

The local proxy URL (http://local_proxy@127.0.0.1:PORT) changes port on each session, confirming sessions are refreshing
My GitHub settings show a "Claude Code" fine-grained PAT and SSH key, both marked "Never used" — suggesting the actual auth was always handled by an internal platform credential, not these tokens
That internal credential appears to have expired or been revoked on Anthropic's side
Environment:

Claude Code web (claude.ai/code)
Repo: github.com/alteonsolutions/mapper-scripts (personal account, not org-restricted)
Platform: Linux

Same issue over here....

[tunaon]

Same issue over here.... Too...

FYI. I encountered the same issue with claude code web.
I worked around the problem by specifying my github pat in a prompt.
Then the claude code web session successfully executed git remote add github https://github.com/redacted/redacted.git && git push https://github_pat_redacted@github.com/redacted/redacted.git redacted 2>&1

[AlteonSolutions]

Refreshing and providing a new PAT worked for me as well...not sure why it stopped working suddenly but it's working now.

same, I generated a PAT and was able to have a claude code session use that. I also found that even a new CCW session has the same problem, and I need to give it a PAT.
