Hi,
My app's Railway-provided domain is showing an invalid SSL certificate error:
Domain: web-production-f1ba6.up.railway.app
Error: net::ERR_CERT_AUTHORITY_INVALID
Browser: Chrome 143 (macOS)
Started: December 25, 2025
Chrome shows "Your connection is not private" when accessing the domain. All API requests fail with certificate errors.
I've tried:
- Incognito mode on two browsers - cleared caches, etc.
- Redeploying the app
- Checking Railway status page
Could you please regenerate/renew the SSL certificate for this domain?
Thanks

try removing the domain from your service settings and then adding it back again. railway will regenerate the ssl cert automatically. should fix it in a couple mins
if that doesn't work, go to your service settings → domains → click the trash icon next to your domain → wait like 10 seconds → add it back. this forces railway to reissue the certificate
