I reinstalled window, game. Didn't help solve the problem. I updated the firmware of the router, then completely changed it to another one, contacted my provider. Everything has been tested and works great. But it didn't work for the game. I opened the recommended ports, it did not affect it in any way. This error occurs only in strikes and other activities with and without players, as well as in raids, but very rarely in raids. And in the same flight all the time. It is not possible to play, all the time spent is wasted.
