There have been a whack of users recently from UK/EU regions complaining of lost cloud files and no server or bad server connections. I don’t have the IPs handy but fire up your network and open the network resource monitor (windows). Then start up the sim. Do you see outgoing but no incoming or does the net traffic seem to go both ways at a reasonable rate?
I ask this as I have seen two new posts today alone where people can’t get into the sim or have no server connection when they do.
