so again - it mean that ports are open. yes?
but what happens when server is hibernating?
why this error only appear on empty server?
Sorry, I didn't see it was when the server is hibernating.
Yes this could be because of hibernation, since activated it leaves your server "offline" to save resources, suspend it let's say.
Try disabling server hibernation to see if it resolves.
