When I connect from my client (https://:8080) I can log on but get the following and, even though I’ve followed various links to try and understand what I’m supposed to do, I just don’t get what I’m supposed to do here especially as I initially only want to run the thing on a local network.
I’ll be straight… I was working on the assumption that I would log on like I would when I had Nextcloud installed manually on Ubuntu and then start adding things from there. The videos I’ve watched all seem to be suggesting NGINX and I really don’t want that at this point, I just want to get on with configuring things from the Nextcloud control panel.
Any advice as to how I get past this screen and to the Nextcloud standard stuff appreciated.
