Problem with freezes and high ping

After the last update, there was a problem due to which the warzone became unplayable. In the lobby, while waiting for a fight, the ping increases from 44 to 142 gradually, before it was always at 30. In the game, this results in constant freezes with the appearance of the "Packet Loss" icon. Because of the friezes, it is naturally impossible to play. The adv_options file is configured, there are no problems with the Internet.
