I'll start. Did you know you can run a headless version of JD2 on a raspberry pi? It's not the greatest thing in the world, but sometimes its nice to throw a bunch of links in there and go to sleep.
Are you using port forwarding? Back when I had PIA (before they sold), they would randomly assign you a port when you connected which caused major issues with QBit as you have to set a fixed port number. Not sure if that's your issue but it might be worth looking into.
