I have external DNS and when I change it to point to my droplet and navigate to that page in a browser, I get an error saying that the connection is refused.
I checked the apache error log at /var/log/apache2/error.log and it says:
[Sat Feb 26 21:11:09.582275 2022] [php:warn] [pid 48772] [client 18.104.22.168:61443] PHP Warning: Undefined array key “host” in /var/www/html/wp-includes/canonical.php on line 699
I’m not sure what to make of that… anyone know what the error is or how to figure it out?
