"Has left the session" connexion issue

[Valdzor 1]

Hello, got into online racing recently but after some laps I always have some sort of connexion issue.
The game says that the other drivers have left the session and I can continue driving but it's like driving against AI.
Of course the other people didnt left...It's weird but I can't play like this
Any idea?

Check any firewalls and security software, maybe restart your router. Also, make sure your updates are done and PC restarted.

I'm only using the standard windows firewall, all updates are OK, and my router is new
I tried a clean install of the game

What is your geographical location and speed to the players in the zone you are playing online?

Can you post a speedtest to a Parisian server?

It's not like you lack bandwidth. How about drivers for your network card? Wanna post a dxdiag?

Killer Control Center is UWP app in Windows Store (must be DCH driver), just search for it, maybe useful!
