The server connection is broken (Call of Duty: Modern Warfare (2019))

All good day, I recently encountered a problem, can't log into the game and I have an error:the connection with the server is broken.





Scoured the Internet but as such the solution is not a problem.Began to think for myself what am I to do,immediately became sin on your ISP as I connected to the Internet with a speed of 200 Mbps and decided to check maybe the problem is in the ISP, plugged in the phone to the computer and gave the Internet with him,in the end, the game start immediately without any problem.Then decided to experiment and connected the phone to Wi-Fi pre pulling the cable coming from the router to the computer and you know what? the game has started. Called the provider and asked to change my router because I think that was the problem and that is transmitted by cable to the Internet. How to change the router to complete the subject: if this resolved my problem.
