Directly from big N:

This error code generally indicates that your network is not optimal for peer to peer connections, this may be due to the ISP, Internet connection speeds, or due to your network's NAT type.

Check your connection NAT type in the switch's network settings. If it's "D" try another router.

I checkd, it is Nat B. How can I change it?

NAT B should be fine for online playing. Your downloads speed should also be over 3 Mbps.

My NAT B with 22.2 Mbps

Disclaimer, you shouldn't need this and it is not your issue if your NAT is type B. If you want to get a Type A, completely opened optimal NAT you have 2 options.

1. DMZ the Switch
2. Port range forward

So I range forwarded EVERY port for my Switch and it actually did the same as DMZ for it.

Try this if you know how, it should give you a Type A NAT.

Otherwise at this point it's either Nintendo's servers screwing up the matchmaking or you're incredibly unlucky.
