The GitHub App "Cloudflare Workers and Pages" (cloudflare-workers-and-pages) can no
longer connect to my account. This started showing up as a Cloudflare Workers build
error: "The project is linked to a repository that no longer exists."

What I've found trying to fix it:

1. In Settings > Applications > Installed GitHub Apps > Cloudflare Workers and Pages >
   Configure, the "Select repositories" search box spins forever and never loads a
   repository list.

2. Switching that app's repository access to "All repositories" and saving did not
   help — Cloudflare's own "Connect to a repository" dialog still shows "No matches
   found" for my account.

3. Trying to reconnect from Cloudflare (both an existing Worker project and a brand
   new one, since I tried creating a fresh project to rule out a project-specific
   issue) redirects me to this URL, which returns a 404 instead of a permissions
   screen:

   https://github.com/apps/cloudflare-workers-and-pages/installations/new/permissions?target_id=321898542

4. I checked githubstatus.com and everything shows operational, so this doesn't look
   like a general outage.

Thank you.

This looks like a stale or broken GitHub App installation rather than a repository-selection problem. The app page itself is currently reachable, and the normal installation route is:

https://github.com/apps/cloudflare-workers-and-pages/installations/new

The most reliable recovery path is a full uninstall and reinstall, which is also the procedure Cloudflare documents for repository-access errors:

1. Open https://github.com/settings/installations.
2. Select Cloudflare Workers and Pages.
3. At the bottom, choose Uninstall Cloudflare Workers and Pages. Merely switching to All repositories does not rebuild a damaged installation.
4. In Cloudflare, open Workers & Pages, disconnect/remove the stale Git account integration if it is still listed.
5. Start the connection again from Cloudflare with Create application / Import a repository → Add account → Install & Authorize. This ensures Cloudflare receives the new installation ID and token instead of reusing the old state.

Cloudflare official instructions: https://developers.cloudflare.com/pages/configuration/git-integration/github-integration/#reinstall-the-cloudflare-github-app

GitHub also documents the canonical third-party app installation route here: https://docs.github.com/en/apps/using-github-apps/installing-a-github-app-from-a-third-party

One useful isolation test is to open the canonical installation URL above in a private window after signing in. If that page works but the Cloudflare-generated /permissions?target_id=... URL still returns 404, the failing state is most likely on the Cloudflare connection flow. If even the canonical installation route fails for the personal account, capture the GitHub request ID from the 404 response and send it to GitHub Support.

Be aware that uninstalling the app temporarily stops new Workers/Pages builds for every repository connected through that GitHub account, although existing deployments remain hosted. After reinstalling, reconnect the affected project and trigger a new deployment.
