Trade issues limited to SWSH???

NAT type: B
I can connect to internet in game, shows random ppl and gives the cards both in y-comm and while playing, however, surprise trade and code trade are stuck on searching forever, a good 5min+. I cannot visit someone elses camp either with it coming back with "unable to connect to other console(s)" "NAT traversal process has failed"

10-25ms ping when tested on pc fttp (fibre internet) SV trades work fine
