@anselmschueler thats not the answer unfortunately, thanks for the effort though. lsof -i :port shows nothing, ss -tulpn shows udp UNCONN 262656 and no corresponding pid/program, it still has stuff in Recv-Q. The conan exiles server went and ghostblocked udp ports 7777/7778 and started on 7779 7780 the next time I started it because the first two are indefinitely blocked.
