Try redeploying your services. If you’re using a custom domain, try removing it then add it back. Update DNS records if necessary.

quick/best solution IMO is to spin up Gitea service inside railway, then do the mirror/migration of github repo, so it's more secure, self hosted git is cool, transfer of project to client/new owner is always super easy, and deployment times will definitely improve.

in railway it's super easy, you just select template and follow the gitea documentation
