Hi, seems all USA servers just died, can't stop it on my end.
It gives this error;

There was a problem finding the host node. Please try again.

Thanks.

Seeing the same on my side, I can join an NL server but not USA. Was struggling to figure out why my insim app wasn't connecting...

"Stopping the host : Sunny South Raceway
There was a problem finding the host node. Please try again.
Back to host details - Back to host listing"

I can't connect, but my friend can. However when he tries to join it says it cannot find the car on the server.

Also, I have been having trouble ALL day with mods not downloading!

Yeah it’s frozen on the host panel, and yeah since usa host down it’s not able to download mods etc

We learned about that from a technical support email yesterday. I've only come across this forum post now.

There was some kind of connection problem. The server was restarted and then the same issue came up a few hours later, was restarted again and seems to be OK for now (around 16 hours). We don't yet know why it happened. It has been running for 3 years without a fault.

Feel free to post here again if the fault comes up again. I should get the email notification.
