We are currently running version 2.2.0.470 one primary and two secondary servers at satellite offices. From time to time we cannot log on using https to the primary. So far either restarting the services or rebooting the server has resolved that issue. Today I had the same issue but rebooting has not resolved the issue. The server seems to be authenticating clients just fine. I can log on to my secondary servers without issues as well. Not sure what else to do, possibly reboot my secondary servers? A possible bug with secondary and primary were they have to be rebooted in s specific order? Normally the server is running within 15-20 minutes but it has been initializing for about an hour now.
