Can not connect Replit to Github after using Codex resulting in a major mess

REPLIT Git Error
UNAUTHENTICATED
Failed to authenticate with the remote. Please ensure that Replit has access to this repository on GitHub.
GitHub Integration Fails After Major Replit Project Restore
Environment
Platform: Replit
Project Type: Full-stack web application (TrialSage regulatory platform)
Language/Framework: JavaScript/React frontend, Node.js backend
Repository Size: Medium-large (regulatory compliance application)
Issue Description
After performing a major project restore in Replit, I'm unable to connect to my GitHub repository. The project was previously working correctly with version control integrated, but following the restore, all Git operations fail.

Symptoms
Git commands return authentication errors
Version control tab in Replit shows "Unable to connect to repository"
Push/pull operations consistently fail
GitHub authentication appears to be rejected despite re-entering credentials
Repository history is visible but cannot interact with remote
What I've Tried
Regenerated GitHub personal access tokens with appropriate scopes
Updated remote URLs using git remote set-url origin
Cleared Git credentials cache
Verified environment variables and secrets for GitHub authentication
Confirmed repository permissions on GitHub side
Re-authenticated through Replit's UI
Checked for SSH key issues in authentication
Error Messages
When attempting to push changes:

remote: Invalid username or password.
fatal: Authentication failed for 'https://github.com/[username]/[repository].git/'
When trying to pull:

fatal: could not read Username for 'https://github.com': terminal prompts disabled
Additional Context
This is a complex regulatory application with many dependencies and a large codebase. Creating a new Repl and migrating everything would be extremely time-consuming and risks losing configurations. The restore was necessary due to system issues, not Git-related problems.

Any assistance in re-establishing the GitHub connection without creating a fresh project would be greatly appreciated!

Feel free to customize this with any specific error messages you're seeing or additional details about your particular setup.

I'm having the same problem, did you sorted that?

I had to go the connectors section of https://replit.com/integrations and activate GitHub to get this working

It sounds like the restore may have broken Replit’s stored auth links, so re-establishing the GitHub connection through a full disconnect/reconnect usually helps, similar to how meticulous processes like pet transport uk to usa require resetting each step properly. You might try removing the GitHub integration entirely in Replit and reconnecting so it refreshes tokens and remote bindings cleanly.
