Unknown error after network problems

After having big problems connecting with friends in the game "7 Days to die" (always kicks them out as soon as they join) our party crashed, stating the error code 0x8923401C and "your current network settings are blocking the party chat". We are currently
all 3 not able to start a party, nor an online game.

Google won't tell me anything about this, not even with the code. Is this a temporary microsoft based problem or may this be able to do any harm to our hardware?

Unknown network error?

Hopefully this is the right place, and won't be ignored. Whenever I try to play GTAO I'm constantly being told there is an unknown network error, and when I check my connection it's perfectly fine except for the xbox service alert. But that seems to only
deal with minecraft and apps.
