EDIT: Nevermind, I had forgotten about the LAN_NETWORK variable of the docker... whoops!
So I downgraded from the latest version to get back on 1.3.15 (binhex/arch-delugevpn:1.3.15_18_ge050905b2-1-04), and while the Web UI works fine, I'm now totally unable to connect remotely using deluge thinclient.
Both the server and the thinclient have the same deluge version (1.3.15)
"Allow remote connections" is checked, daemon port is default (58846)
Firewall exceptions are set for deluge
I triple checked the username and password in the auth file.
Still getting a red light on the thinclient connection manager. Any ideas?
