Rutorrent not working, invalid port v6.33.3

Did a fresh installation of Buster onto version 6.33.3.

I get invalid port in the tracker tab when trying starting a torrent.

I’ve tried the DHT update in rtorent.rc and port forwarding on my router, with no luck.

Rtorrent/Rutorrent is without question great, but the hardest to configure.

I’ve tried solutions in other threads, the chown permissions should not be an issue as these were supposed to be resolved in v27 release.

Any ideas?
