When we install Sophos Endpoint on computers running Windows 8.1 or servers running Windows Server 2012 R2, there will be a communication error between Endpoint and Sophos Central as follows:
ERROR Request: WinHttpSendRequest failed: 12029
In this article, techbast will show you how to fix this.
The reason for the communication error between Endpoint and Sophos Central is because computers running Windows 8.1 and Windows Server 2012 R2 servers have not updated Microsoft’s KB3172641 patch.
