I have my website at veliz.netlify.app. I have a custom subdomain veliz.rbind.io that I am trying to add and verify.
The error I get in Domain Management>HTTPS is:
SSL/TLS certificate
We could not provision a Let’s Encrypt certificate for your custom domain.
Please read our troubleshooting guide for some tips on what might be happening.
To provision a certificate automatically, Netlify needs to go through a domain validation process on your behalf. This step cannot be completed unless the DNS records for your custom domain are already pointing at our servers.
I used to have no problems with this but eventually the certificate expired and now that I updated my website it seems to not be working still. I can access https on the netlify.app domain but not on the rbind.io domain.
Thanks,
Esteban
