If the hostname of CyOPs machine is changed to two level subdomain(e.g. name.subdomain.domain.com), the new certificate must contain *.subdomain.domain.com apart from *.domain.com in the Subject Alternative Names(SAN) section of the certificate.
If your certificate only contains *.domain.com as part of SAN, you will see `No subject alternative DNS name matching demo.subdomain.domain.com found` in `/var/log/cyops/cyops-gateway/gateway.log` and `/var/log/cyops/cyops-notifier/notifier.log` files.
Therefore, make sure you ask to put both *.subdomain.domain.com apart from *.domain.com in SAN part of the certificate from you certificate issuer.
