Agar.io invalid party code...?

[Casablancovich]

Since a month or so, i have trouble joining my friends partys trough wifi or own simcard. (I play agar.io with the samsung note 9)

The thing is i am the only one with the problem. My friends dont.

I tried to use dns changer but  it still doesnt work trying to join other party code of my friends 

Any help please?
