@Faya, I have the same issue. Since today I receive this error message. Your Steam name - S@msung (Playing Steam PC) A picture of the error that you're are getting - see below Are you running any UDP telemetry tools? NO Validating F1 2019 was successful but did not solve this issue! UPDATE: After second time Validating F1 2019, it was possible to play online again. So my issue is fixed.
