Okay, ports have been forwarded.
I will ask everyone to update gpu drivers.
We will see what happens next monday when we race as usual. I will try remember to post results here afterwards.
Thanks for your help and fast responses
update: Viper tells me he has suffered with an ongoing performance bug related to his 1060 nvidia gpu. I also have that card and have had no such issues.
update 2 electric boogaloo: 2 other league racers have 1050ti and 1060 and experienced no issues (connection or performance)

We have an international league with people from UK, Netherlands, Belgium and possibly others but I don't usually ask people for privacy reasons
Resetting the modem for me is not often possible when my partner Izzi280 (also in the race) is streaming on the same network. We also have no issues in many other games with dedicated hosting options (arma 3 for example as a host). Is the game reliant on UPnP? Is there port forwarding options?
We had 1 new driver (Viper_22b) who signed up at the start of the session in Spain (1 race ago) and also joined for Canada (previous race). Both these races had Lambert's issue happen in the exact same way.
If 'saving sessions' in league mode wasn't also bugged we would be using that to circumvent bad race connection starts. I'd rather not use that option if possible to save the recursive returning to previous quali issue.

Ignore the name, this was like the 5th iteration after we had to restart it so many times because of 'option lockout' after creation time
