First this seems to be a client issue, because I'm not getting reports of others being affected, but I have seen this happen with different clients over time with Sophos and the only resolution I've found so far has been to restart the computer.
I'd like to find out "why" it's happening and if there's a resolution short of restarting the entire computer.
In today's example I was connected with Sophos Connect client on an IPSEC VPN connection. This appears to still be up and intact.
I was working over VPN, had an RDP session open as well as a connection to an internal website and SQL server all of which required my computer to authenticate with heartbeat.
"without any warning" the firewall has now deemed my computer as to not be authenticated via heartbeat which means all of the resources I had open are no longer available if they require heartbeat authentication.
I verified that Sophos Central shows my computer has a green status. I don't see any windows events that would have contributed.
