Problem when I launch Null’s Brawl

Hello !
I have a problem : I recently installed Null’s Brawl on my IOS device but after a few days, this message appears (your site is blocking me and I can’t send it)
I don’t understand because I’m connected to the internet and I trusted the application in settings…
Please help me as soon as possible as I love your application and would love to play it !

Problems with “all for one” map. From 6 level on, the game crash and disconnected from the server.
