Apache keeps saying: You configured HTTP(80) on the standard HTTPS(443) port!
Solution 1:
I was getting the same message. It turned out to be a VirtualHost definition that was missing a ServerName directive. In my case:
<VirtualHost *:443>
ServerAlias hostname-old.domain
Redirect permanent / https://hostname-new.domain/
</VirtualHost>
Which should have been:
<VirtualHost *:443>
ServerName hostname-old.domain
Redirect permanent / https://hostname-new.domain/
</VirtualHost>
