Constant error message.

Constantly getting desynced at the very beginning of mut games with friends and kicked from matches even though I’m pulling hardwired 900 Mbps and idk why, I’ve cleared the cache, I’ve rebuilt the database I’ve redownloaded the game, I’ve restored licenses. In over 10 years of playing madden I’ve never had this issue and don’t know what to do? Message error code 

“miscservicegateway_err_system”
