From looking into this it appears to be related to an ISP issue regarding ISPs trying to localise peers or some nonsense.
To confirm:
1. When did you start having this problem and has it always been this same error?
2. You have DHT/PEX (peer exchange) disabled
3. You don't have UDP disabled
4. Can you try download a torrent from
You must be registered to see the links
and let me know if it works?
5. Do you have a VPN you can test on?
6. Do you have access to any sort of a firewall or other that might be at your house?
