Need help with 2123-0011 error code on modded switch.

[Gostw]

I modded my switch and mine is unpatched erista.
I'm using emummc only so I'm not get banned.
My hos and emummc is both 18.0.0 firmware version.

When I play some games which has leaderboards(like watermelon game) error code 2123-0011 pops up.
But if I press OK then I can still continue the game and there is no crashes or something.
I think this error comes when swtich trying to connect Nintendo servers. But of course on emummc nintendo server's are blocked.
If I turn airplane mode on, then there is no error codes come out.
Is there are any way that I can prevent this error message pops out?

I deleted all my original nintendo accounts in emummc and made new one for only emummc.
First I didn't linked it via linkalho but whenever I try to launch games, switch asks me "Do you want to link you account?" so that annoys me and I linked my acc.
After I linked my acc this 2123-0011 error pops out.

In my opinion, it's very natural that this 2123-0011 error pops out.
Because, when switch is connected to wifi then of course switch tries to connect nintendo servers when I launch some games(which originally made to try connect nintendo servers and get some high scores or etc when your switch is connected to wifi)
But, there is some programs for preventing ban(ex. exosphere) and those programs blocks to connect all the nintendo servers.
So switch can't connect nintendo servers despite it's connected to wifi. That's the time when switch shows error code.
When switch is offline(airplane mode or not connected to wifi) it can't reach nintendo server so switch doesn't try to connect nintendo server. That time error doesn't pops up.

Anyway, What I want to know is
Is there are any way that I can prevent to switch pops up that error code 2123-0011?
It's okay to use airplane mode when I play kind of those games but that makes me annoying to turn on/off everytime.
If anyone knows about this please give me some advices! Thank you!

Hi all,

Playing Hogwarts Legacy,

Same error code 2123-0011 for me when WiFi is active. Picture1
When in airplane mode, the switch asks to deactivate it. Picture2

Switch is on CFW 18.0.1 and ATM 1.7.0.

Using linkalho-v2.0.1does nothing and the error code persists.

It seems that switch-sys-tweak can provide a satisfactory answer, but, where to download it, and how to configure it?
Is this really the solution?

I am attentive to your comments and suggestions.
Regards.

Yo gars, j'avais le même problème, enfaite il faut supprimer tout ce qui a rapport avec la sysMMC. J'ai donc supprimer tout mes comptes de la sysNAND avec DBI installer, supprimer tout les jeux des la sysNAND qui sont present sur la emuMMC, supprimer toutes les sauvegardes etc.. faut supp tout ce qui a rapport avec la sysNAND et tout marchera a merveille.

For the english speaker, the solution is to delete everything that come from your sysNAND that is in your emuNAND, that means: saves, games, users, etc...
