Hey there! We've found the following might help you get unblocked faster:

• 🧵 Github actions with Railway CLI requires login?

• 🧵 Preview deployment where frontend needs a specific URL from backend deployment

• 🧵 Token for GitHub Action

If you find the answer from one of these, please let us know by solving the thread!

In the environment that you are making the preview environment from, is there a custom domain attached or a Railway generated domain attached.

I have my dev and prod environments, which have custom domains attached. no railway generated domains

I think we do require a Railway generated domain as we can't extend the custom domain for you.

what you mean is, I should also have railway generated domains on my dev and prod environments?

For me, the expectation is that railway will generate the preview link (since it is meant to be temporary), regardless whether I have a custom domain set or not

also, i'm not expecting the PR generated domain to extend my custom domain, it should extend Railway's as though one clicked "Generate Domain"

Hi there,

As Angelo called out you need a Railway-provided domain configured for your service/environment in addition to the custom domains you currently have set up. Read more in the Docs on Domains in PR Environments.

Christian

All good, thank you

I think it is working fine now as per the recommendation.

Glad to hear it! I'll go ahead and mark this thread as solved, but let us know if you run into anything else.
