Change hostname fail

I changed the hostname and get this error

Mar 21 11:22:53 server NetworkManager[554]:   [1584789773.8453] policy: set-hostname: current hostname was changed outside NetworkManager: 'server.craven4sale.com'

Cannot restrt apache.

Update:

I had created a subdomain for server.craven4sale.com.  When I tried to change the hostname to server.craven4sale.com I ran into the problem.  Deleting the subdomain fixed problem.  But new issue, no intermediate certificates were created causing bad cert.
