Failed to connect to instance, disconnect

Heya

im getting constantly disconnected from game, failed to connect to instance when i try to teleport to someones hideout.

I have cleared caches, tryed all renderers, reinstalled game, cleared OS temp files etc, removed all MTX and chanced hideout.
And tryed different servers.
I still cant teleport to my friends hideout without an error and disconnect.

i did not have this problem earlyer in this league, it may have come after the gauntlet update, i dont know.

noticed now i cant log in with japan or singapore realms.
is that a sign of something ?

Same problem is throught steam and standalone game.
this problem must be from the gauntlet update.
