Failed to protect computer

Hi

We're rolling out a test Sophos Central implementation. 

When we run the Sophos endpoint installer on any windows device, the install warns it might take 15 minutes to install. Once it's done, the Central portal reports "Failed to protect computer" for each device. This description for this is that the agent was installed but hasn't checked in for one hour. 

If we check the Sophos Management Communication System client logs on the endpoints we see loads of these;

503 Service Unavailable: Back-end server is at capacity: sent=0 rcvd=0 elapsed=249ms

 

This relates to a series of Amazon cloud instances mentioned in the logs. 

 

Any ideas whether this error actually means what it suggests or what we can do to nudge the devices in to connecting?

We've tried a number of devices, rebooting, removing, reinstalling.

  • Hi Olly

     

    It's probably not much help, but I'm facing the same issue.  We rolled out a new Sophos implementation a week ago that was almost flawless (one or two older computers caused problems), yet today I cannot get a client to install fully.  Every time I get the same 'Back-end server is at capacity' error.

     

    Is the error appearing in your McsClient.log file after a POST statement like the one below?

    POST https://dzr-mcs-amzn-eu-west-1-9af7.upe.p.hmr.sophos.com:443/sophos/management/ep/register

     

    The guidance I've found on the Sophos support pages suggests doing a PING test, NSLOOKUP and a telnet connection on port 443.  I've tried all of these and although the NSLOOKUP check works, the PING and telnet tests fail.  I can only assume at this point that the Amazon Web Services instance I'm trying to connect to is either offline or overloaded.

    Yes, exactly as you describe here. 

     

    Fills me with confidence :(

  • Dealing with the same issue. Trying to do a reinstall on an endpoint because of issues with the client, but can't uninstall it because it is in the middle of updating, but taking forever because it can't communicate with the update server. Nothing but '503 Service Unavailable: Back-end server is at capacity' in the logs. Come on Sophos!!
