Sophos Connect Connection reset from gateway

Been searching around google and discussions in Sophos Community and cannot find the answer for my issue.

I'm having one user using Sophos Connect who can successfully sign into Connect through the connection file. However they are not able to access network resources




After about 10 seconds however I receive the below error: Received connection reset from gateway IPADDRESS 8443 tcp-client



Using their same connection file and credentials on my computer I have no issues. We've uninstalled and reinstalled the Sophos Connect Client a few times. This happens on their home network and mobile hotspot. There is another discussion board out there with this same issue but that was never solved / had a conclusion. Any help would be greatly appreciated!

  • Hi guys,

    One of our clients has exactly the same issue at one of their sites...

    Only 1 machine out of 20 constantly disconnecting (resets approx every 10 seconds) when all the others are fine..

    Its definitely related to the machine itself - I installed my own profile onto the affected machine (which works fine elsewhere) and it resets constantly..

    Affected machine is a Lenovo Carbon X1 only around 3 months old, Latest windows 10 with all updates installed

    I've  reinstalled Sophos connect, network drivers, applied every available update from MS and Lenovo

    I tried several different networks as well as on site - exactly the same from everywhere...

    Looking at logs on the firewall, it connects, authenticates fine then disconnects after 10 seconds or so

    I'm out of ideas...  

    Any help would be appreciated...

    TIA

  • Have you tried with the different ISPs ?

    Thanks & Regards,

  • Yes, even with my mobile hotspot from which my notebook (with the same profile) works fine...

    Without question its something to do with the computer itself...

    Thanks

  • Further to this, I've just done more testing and narrowed it down to the wireless adapter in the notebook..  Connecting using LAN port and even a wireless USB dongle works perfectly...  This Lenovo X1 Carbon has Wi-Fi 6E AX211 160MHz wireless adapter.  Doing a search on google, others are having Sophos issues with the new Dell notebooks with the same adapter...  What now?  please help..  Thanks
