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 "master" appears in the dropdown with the error "Connected branch does not exist". My actual branches (including master and dev) don't show up in the list.

Waiting several minutes for sync, but nothing works.

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