Hey there!
What DNS provider do you use for that domain?

Im using namecheap dns, it was working and it just stopped, i just renewed my domain i dont know if that is the issue

domain is instructsphere.com

And i already talk to namecheap they said you the provider must give me the proper ssl connection the issue is not from their side, i have customer visiting my website i cannot have this at all as a education software my business is built on trust and safety i cannot be out of service for multiple days that really sucks

Domain renewals can sometimes reset or modify DNS records, which would break the SSL certificate validation. Check your Namecheap DNS settings to verify the CNAME or A record for instructsphere.com is still pointing to Railway. If the records were cleared during renewal, re-add them and allow up to an hour for the certificate to provision. You can test the connection by running openssl s_client -connect instructsphere.com:443 -servername instructsphere.com to see what certificate is being served. If your DNS records look correct and the issue persists after an hour, let us know and we can dig deeper into the certificate status on our end.

You might need to remove and readd the domain on the Railway service.

I already removed and readd the domain twice, the Cname record is still pointing to railway in namecheap but it is stucked on instructsphere.com

Port 8080

·Validating domain ownership

This is inside settings for the application, i have ven deleted and redeploy the app but still giving me this issue that really really bad for me right now

instructsphere.com is working for me. Domain validation may take awhile as DNS changes may not propagate immediately. Can you confirm if this is resolved?
