Error code BLZBNTBGSO000003F8. (Call of Duty: Modern Warfare (2019))

Before the release of the second season didn't have such problem at all, now I can catch almost every rink, and maybe a couple of hours not to be disturbed. All decisions recommended Blizzard already tried, no use. The provider does not think 25 October to second season everything was fine. Who can faced, prompt decision.
