My GitHub pushes suddenly stopped triggering builds on Railway, so I tried to fix it by disconnecting and reconnecting the GitHub integration.

Now the repository appears as connected in Railway, but no branches are detected at all. When I try to select a branch, only "main" appears in the dropdown with the error "Connected branch does not exist". My actual branches (including master and main) don't show up in the list.

What I've tried:

• Uninstalling the Railway GitHub App from GitHub (Settings → Applications → GitHub Apps → Railway → Uninstall)

• Reconnecting the repo from Railway

• Creating a brand new service and connecting the repo fresh

• Waiting several minutes for sync

Nothing works. The GitHub App shows "never used" on GitHub's side, confirming the connection is fresh but Railway is not fetching the branch list.

Note: I cannot disconnect GitHub from Railway's account settings because my Railway account is linked via GitHub login.

This was working perfectly before — I didn't change anything in my repo or branch names.
