Out of the blue today, we began to receive, "The license does not permit you to log in at this time. Please contact your Administrator." after authenticating to the user portal, even when using the created VPN Administrator account, so I am unable to log in and see if there is something misconfigured. On the "physical" side, I can log in with root and tail the hypersocket.log file and see the authentication was successful.
It's a pretty plain setup, 4 users, nothing special like AD integration.
