Subject Re: [users@httpd] Stupid question time - VirtualHost
Date Wed, 06 Feb 2019 21:09:55 GMT
Maybe related to using a name instead of an ip address with Listen

documentation of Listen directive specifies you should use ip address
too. Is that name correctly resolving to the specific ip address in
the system?
