Management communication issue

Hello guys, 

A few of my server machines are showing medium/high alerts due to an issue with Management communication. 

In the Endpoint Self Help tool I get this warning: 

"Unable to determine management communication status. Does the MCS client log exist/is it accessible at 'C:\ProgramData\Sophos\Management Communications System\Endpoint\Logs\MCSClient.log'?" 

The log exists and I have posted it below. 

Based on the log it seems to be an issue with Authentication with the HTTP server, or I suspect maybe the server I'm trying to connect to is incorrect. 

If any of these are true, how would I go about a resolution?
