Unable to check lobby server / Unable to update session list from lobby server

[OneEyedNinja]

I as the GM, when I try to "Start" my campaign, receive message "Unable to check lobby server"
My players ALL are receiving the message "Unable to update session list from lobby server" when they attempt to join campaign.

I rebooted the Lobby server as soon as I got the notification; I'll have to investigate the logs tomorrow.
