Hacking Lan-play not working in Splatoon 3

[Kas_L05]

I tried using lan-play to join some friends in The Shoal, but I think the Switch is failing to connect on my pc.

This isn't the first time I've used the program, last year I used it to play games too, but it worked normally. Now, for some reason, it no longer connects to any game. When I press the combination to activate Splatoon 3's lan mode (ZL+ZR+L Stick), the game doesn't recognize it and returns me to the Plaza. The same thing happens in Splatoon 2, except there the game keeps loading infinitely

Does anyone know what could be causing this? I've tried changing the iP, using another server and reinstalling the programs on the pc.
One thing I noticed is that the program on the PC changes when I access homebrew from the photo album, then it switches to “IConnection::IConnection”. But that's it, the game itself doesn't recognize it.

Which Splatoon Version you are using, our lanplay group currently play on 9.3.0 and everything worked fine

I'm using the latest version of Splatoon (10.0.1) on my hacked switch. It worked before, but after I updated everything, it no longer connects.

In the official system it connects fine, just not in the custom firmware. I think it has something to do with the connection on it, since although it connects on wifi, nothing that requires a connection seems to actually work.

Do you have a 100% save file？

Unfortunately, no. I use my own save

I don't have other players to test, but using CFW on my switch and an OFW switch lite, I can do LAN on Splatoon 3 with eShop copy on CFW switch, and Physical on Switch Lite. I have tested OFW and CFW on my switch, and it connects to the Switch Lite anyways. I have no idea what is going on, but best of luck.

I have tried to update some games from my Switch 2 to my hacked switch 1 (smash, clubhouse 51 games and some other) but is says error even having the latest fw update on both. I can't find any other way to get the latest update to play in LAN mode.

I recall Animal Crossings had a similar issue with local LAN.
You both needed to be on the latest/same version else it would just refuse to work over the local LAN.
Maybe Splatoon has this issue as well.
