504 / 8001 MCS Client intermittently timing out connecting to mcs-push-server-eu-central-1.prod.hydra.sophos.com

There seem to be issues on the Sophos Coud Server mcs-push-server-eu-central-1.prod.hydra.sophos.com.

Can sophos please confirm, the server is running as fast as it should and that this issue is not server side? Please do not simply point to the https://centralstatus.sophos.com/ page - this is green.

Over the day we have many 8001 Errors in event log and the Sophos Agent reports Gateway Timeout 504.

The requests go through a SG Webfilter that does no HTTPS interception, and so no AV scanning of HTTPS, it does only logging and category checking. Also you can see that there are all Exceptions set for the Sophos URLs: exceptions="av,sandbox,auth,content,url,ssl,certcheck,certdate,mime,cache,fileextension,size,patience"

The internet connection is fast and available during that times.

Look here, some of the requests take over 2200 seconds for a size of only 53446 bytes!

A normal web request of the Sophos Client usually only takes about 6 seconds:

I found this posts but they do not provide a solution but the issue is out there for some years now.

  • Same issue!

    INFO  200 : sent=0 rcvd=140 elapsed=101ms

    Any solution for this?

    Thanks

  • it seems this is getting more frequent.

    there are some days without these 8001 events in event log, not only weekends, and the next day again a dozend or more

    Sophos has no idea about this issue in their products?

  • Hi 

    Sophos Central is not experiencing any outage and we have checked the same with the relevant team, 504 is generic a gateway timeout error which means that there is an issue with the networking. Could you please check under C:\ProgramData\Sophos\Management Communications System\Endpoint\Logs\MCSClient.log if it is showing 504 error for every communication. If so, we would have to enable MCS message trails to check what is transmitted.

  • Hello, this is not for every connection. It's just randomly failing.

    I re-checked my answer from above: "there are some days without these 8001 events in event log, not only weekends, and the next day again a dozend or more"

    It looks like the issue does mostly not happen on weekends.

    We have similar issue, both with company LAN and domestic WiFi.

    Is it normal?

  • Hi,

    i have the same issue too.

    https://mcs2-cloudstation-eu-central-1.prod.hydra.sophos.com/sophos/management/ep

    Failed with error '504 Gateway Time-out' at 11:29:08 Nov 24, 2020 (UTC+01:00)

    any solutions for that?

    Greetings

  • I've noticed, this is also happening when working remotely/off-site company LAN. So it does'nt matter if the traffic goes through any of our company firewalls from Sophos.

    The issue is happening to Windows Servers and Clients with Intercept-X .

    I took some time to monitor my log files and found an interesting fact.

    : look at the rising ConnTimes. ConnTime continously increases, then a 504 occours, then the ConnTime is significantly lower and keeps rising again until the next 504. I assume thats the moment when your loadbalancing switches over to an other cloud server with less load.

  • Hi, I closed the ticket with Sophos. Very slow and superficial support. They blame our corporate network, for me it's the Sophos servers that have some problems. However it is a sporadic issue.
  • Hi

    What is the server core agent version installed? Have you configured ant controlled updates?
