STAS "Test connection failed"

 Hi there,


I'm trying to set up STAS on my domain controller, and having a few issues.

The STAS Agent and STAS Collector are working fine, and testing okay, but when I test connectivity to the Sophos device, I get a "Test Connection failed." popup.


I have added the rules to Windows Firewall for TCP/UDP ports 5566 and 6677 as well as 6060, and even tried with Windows Firewall completely disabled but still have no luck.


I have checked everywhere I can think for logging but there seems to be no errors anywhere in the logs on the firewall or on the DC itself





Screenshots of error attached.

  • Namit,

    from console, tcpdump "port 6677" and launch the test connection and share what is the tcpdump output.


  • Hi Namit,

    I was able to resolve this issue after a call to Sophos support.

    After a long time debugging, the solution was to go to "Administration" > "Device Access" and make sure the appropriate services were selected for the zone that the DC was in. From memory, you need to make sure "Client Authentication" is selected.

    Hope this helps
