Hi community,

I connected a custom domain to my Node.js

service on Railway but the SSL certificate

has been stuck for over 24 hours.

Current status: "Certificate Authority is

validating challenges"

When I click "Try Again" it shows:

"Failed to issue TLS certificate - An

internal error occurred"

My DNS setup:

- CNAME @ → pointing to my Railway domain

- TXT _railway-verify → verified

The domain is resolving correctly to

Railway's IP (confirmed via nslookup).

The app works perfectly on the default

railway.app subdomain — only the custom

domain SSL is failing.

Has anyone experienced this? Is there a

fix or do I need to wait longer?

Thanks
