Does it say internal error or rate limit?

If you reached the rate limit, then you’d need to wait until next week for LE to issue certificates. Unfortunately this rate limit isn’t something Railway can fix or reset.

Same thing is happening to me please fix your damn servers this is pissing me off I have a site I need hosted and its failling to issue certificate

This may have been related to https://status.railway.com/incident/1QD5978Z. Try removing the domain and add it back after 10-15 mins.

it says: An internal error occurred. Please retry or contact support.

Is there a retry button?
