Hello, before anything else, thanks for this great client i been using since years ago. I never had any issue or complains before, but for some reason, after many years using the program i started getting the error 10003 (not listening to connection) message when i do initiate it, in the end i always gotta ignore the message, but i know it might be affecting my download/upload speed. Here is what i get in the logs. Hopefully someone can help me out.

[17:44:29]  UPNP mapping UDP port 2000 on gateway 192.168.1.1 - command failed with error 718 ConflictInMappingEntry
[17:44:29]  UPNP mapping UDP port 2000 on gateway 192.168.1.1 - command failed with error 718 ConflictInMappingEntry
[17:44:29]  mapping UDP port 2000 on gateway 192.168.1.1 will be retried every 5 minutes
[17:49:49]  socket closed while listening on udp:0.0.0.0:2000 : Bad access (10013)

I decided to use UPNP (i got a static IP and i did open up the port years ago and it has been always working but now it won't anymore) my old port was 22693, i changed to 2000 because i read low number port helps, but it doesn't seem to be the cause

More than one device is trying to use the same port. If you know that isn't true, restart your router and see if that fixes it. Also try temporarily disabling UPNP, restart it and then enable UPNP.
