I tried multiple times, it always like this. (I added another custom domain, different subdomain with this one, it worked within 20 mins)
Could anyone help?
echo | openssl s_client -servername [my domain] -connect [my domain]:443 2>/dev/null | openssl x509 -noout -issuer -subject -ext subjectAltName
issuer=C=US, O=Certainly, CN=Certainly Intermediate R1
subject=CN=t.sni-820-default.ssl.fastly.net
X509v3 Subject Alternative Name:
DNS:t.sni-820-default.ssl.fastly.net
TL;DR
Developers experiencing issues adding a custom domain; verification successful, but stuck at "Certificate is being generated...". Another custom domain with a different subdomain worked within 20 minutes. Use the provided command to check the certificate status.
