Please verify the Railway GitHub App has access to this specific repo under GitHub Settings > Applications > Railway App > Configure > Repository access, then go to your Railway account settings and unlink and relink the GitHub integration. After relinking, use the Refresh button (project canvas > Add > GitHub Repository > Refresh) to force a cache refresh before trying to connect the repo again.

I did this twice. It's not connecting

It's finally working now

i had to give railway acccess too all repos so something is still not right but it's working for now

If the repository belongs to an organization (or if the personal account is strictly managed), GitHub's organization-level security might be blocking it. Check the approval for Railway under the organization's settings (Organization Settings > Third-party access)

If you think it's working. kindly mark this thread as solved.

I'm having this issue too, though setting to allow All Repositories doesn't have any effect. Removing the Railway app from GIT and re-adding doesn't work either. It all seems to be configured ok on GIT, Railway just doesn't want to show any Repo's when trying to Connect Source -> search... 3rd Party apps have been working ok with other providers (Payload etc) so I'm wondering if its a Railway issue.

FYI I've been able to fix this issue as described on this support thread: https://station.railway.com/questions/org-repo-not-selectable-after-transfer-e343e780 where you need to goto your workspace canvas and Add the repository (making sure you have the Railway app setup on GIT). I also needed to allow the Railway app to all Repo's.

It happened to me and I couldn't fix it, so I used the artificial intelligence agent here on the platform and through it, it managed to make the connection, then the next pushes worked automatically
