I can access my Web GUI from LAN perfectly yet when I try to access it from WAN, it fails to load. I know that I have correctly port forwarded because I can access my instance of nextcloud on WAN from the app but when I try to get to it through a browser, it says the server cannot be reached. I think my problem lies in my apache configuration for it.
I determined that it was a problem with chrome on mobile. I checked this morning using different browsers and a laptop and I am able to reach my Nextcloud Web GUI on WAN. I don’t use https because I can’t really afford a certificate at the moment. Thank you for your reply!
To clarify my statement about hosting websites through Nextcloud, I set the DocumentRoot to a directory inside of Nextcloud so I can edit all my html and css through a web browser. Maybe not the most secure or best way to do it, but it works for me.
