Ping jumps every 30-60sec after turning on "League of Legends"

Hello, as in the topic ... Ping (in the console) is normal, but by the time I turn on, or rather enter the game. After some time the ping starts jumping from 35 to 150-250. And so every 30-60 seconds. After turning off the game, jumps stop after some time. In short, these ping spikes are in-game only. I also noticed that this happens after the computer format (new disk), before the format I had no such problems and the ping was normal during the game (I don't know if this information is important). I connect to the router via cable. Thanks in advance for any attempts to help me.

EDIT: Ping spikes now even occur when I'm not using anything or playing: v

The system or some application is not accidentally downloading any updates in the background? Have you checked what is happening in the system's Task Manager, is something overloading the system itself?

I noticed that the problem may be ... Teamspeak; -; When ping spikes appear in CMD, you can see in the processes that Teamspeak uses more "Network", "Disk" and "Memory"

Then follow this lead. The question is whether the application is updating or communicating with its server.

The problem occurs only on one Ts server, on which I was spending the most time ... So just the server's fault?

I don't know that, because I don't know much about online games (I'm not interested in that). The application itself is the latest version? Does it not download updates at this time or does it not refresh its content?

Disable in process manager, and test without it.
