@nix54 This sounds like a port forwarding issue. Our tracker is very sensitive with port forwarding for some reason. In order to get proper upload traffic all the time, you need to make sure that the port your torrent client is using is forwarded through your home router or VPN to your computer, both in TCP and UDP. Without this, you will notice the exact symptoms you seem to be having.
If it's of any help, your current torrent client is reporting that it seems to be using port 63357.
