Apache keeps saying: You configured HTTP(80) on the standard HTTPS(443) port! I have configured an SSL web site using the macOS Server app (version 5.3). When I examine the Apache log, I see this message (twice):

 [ssl:warn] [pid 4120] AH01916: Init: (mydomain.net:443) You configured HTTP(80) on the standard HTTPS(443) port!


I have not made any manual modifications to the Apache config file. I tried deleting the site, then stopping and restarting the web server, and finally re-adding the site from scratch, but the warning continues to show up in the log.

What is wrong and should I care?
Check the configuration file of your website for "SSLEngine off". In my case, this setting had been changed by the upgrading process. Changing that line to "SSLEngine on" solved the issue.
