There’s nothing to do with DNS records.
In my situation, I’ve solved all the problem related to www/non-www redirect with EEv4.0.10 by the following steps:
- Open and check the file
Check if the server name is correct, there are two lines of server name (http and https)
My domain name starts with a “w”. It was abandoned thus wrong name!
Make sure ssl_protocols including all version of TLS
ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
It IS included in the file:
But not this file
By default, EasyEngine does not include TLSv1 TLSv1.1 or SSLv3, this may causes error 503 when someone just type “yourdomain.tld” in the browser address bar when your site was created with SSL + Wildcard + sub:WWW
Also make sure other ssl settings similar.
Hope it help.
