Plesk Completely Unresponsive

[truedojo]

Hello, after a rather random reboot of the server, I cannot login to my plesk servers via my browser and VZMC. I have other VPSes hosted on other servers and I can connect fine. Where should i start to look in terms of a problem? What error logs should I look at? would an upgrade from 8.1.0 to 8.1.1 solve the issue? I can see the websites that are hosted on the unfunctioning VPSes and I can SFTP, SSH into them. Plesk just isnt working...
