The problem in multiplayer. (Euro Truck Simulator 2)

Hi all. I was very much concerned about one problem that none of the admin is not able to help me really, even the main (he wrote in his mail).
The bug is enabled during a multiplayer game when he pleases, but most often noticed in the quite crowded places in locations where a lot of players, sometimes it works immediately with entry into the multiplayer, then multiplayer is empty. He works very subtly. Players just disappear from my game and I don't see them, at the same time, insidious is that sometimes not all players become invisible to me, and sometimes all. At the time, yet I don't see them, I can pass through them without damage to the truck, but knocking them down and driving through them the car. Those tracks that are close in time bug look like
I'm definitely not the only one with this problem, because they saw them myself in the game, and I saw a different video.

from 0:10 to 0:17


6:02 just all spreads, all of them are visible to the user.


Also, when the bug is activated, messages that I write in chat, I can't see, but they go, because other players see them (I asked other players in discorde)
in Taba see such distances.


The title of my problems are Lock inbound multiplayer. On different boards I tried to configure the firewall, tried to configure the router, but nothing helped, maybe it did not. Please help me I get bans for that Taranu people, unfortunately I can't see the video tried to shoot, the fps drops sharply, the computer is not the most powerful.
Thanks in advance.
