Instructions for changing hostnames are provided in the Changing Hostnames documentation chapter.
For CM server the hostname change should be trivial and working fine afterwards.
Is your CM TLS enabled?
Do you get any error message when connecting to the CM web UI?
The CM server logs as asked by @manuroman will reveal if there is an issue.
