It took me a week suffering to get syncthing to work but it finally did. Thank you

I have it set to 0.0.0.0, and I can access it from another pc using the ip:port address. But when I try to access using the domain name it shows the login page but I can't login, it just refresh the page and I can see the error above in the logs.

The forwarding is actually taking place, the problem is that when I write credintials and try to login it doesn't

Sorry it's just 9101, I updated it.

In GUI you can change the port of the GUI and that's what I did, so I can right now actually access it using 192.168.1.2:9101 and it works. Do you have NPM configured in anyway other than pointing? have you made any changes in Syncthing itself to give it a domain name or an address?

I can access using the local ip but I can't access using the ssl domain, I can access it but I can't login for some reason. I can't figure out how to fix it

Where is VPN in demand setting?

That looks great, I may switch to it from nginx, thank you

Thank you, Might try them because duck dns domain is flagged by the browser for some reason and it's worth than no https warning

Mine isn't a proper server, it's just an old desktop

Thank you, looking forward to hearing from you

Does syncthing have a domain name specified I can't find an option to do so

Ohh thank you
