I need help with nextendo prelude

Hello. I never used this app before and today I downloaded it (the latest update). So I followed every step from several videos until successfully logged in from my switch into nextendo network but this error code 2306 0802 that means an Authentication::TokenParseError appears everytime I'm trying to play smash or mk8 online. Maybe I skipped something. Dns is auto, 90dns says almost everything unblocked, account link in prelude is active. I don't know what else to do, help!

Official firmware 22.5.0 Atmosphere 1.11.2 Prelude 3.5.1

Edit: now that i blocked everything by copying emummc.txt file into atmosphere host carpet now I have error 2155-8807.
