Question regarding the use of your own domain and without proxy

[LightRO]

Hello, I would like to use this network without proxy just like the official Pretendo does.

For this I have bent all pretendo.cc and pretendo.network addresses in the src and pointed to my URL.

I have also converted Nimbus. At the moment, everything is actually working so far. Account, friends, Juxt work without any problems. However, if I want to play Mario Kart 7, for example, and go to Online, I can select Global, Versus Race and then select my respective character. Then I can search for players.

If I now add a 2nd 3Ds and do the same, the error code 006-0612 appears on the 2nd device after a while.

In proxy mode, however, it works without any problems. I know that I have rebuilt mine a lot and it will be difficult to get help, but maybe someone can help me and solve the last error I have here. Or give me a tip :D
