When running a CA Access Gateway (SPS), when it tries to connect to the Policy Server, the Policy Server reports the error:
Bad security handshake attempt. Handshake error: 3156 Handshake error: Failed to receive client ack. Socket error 97 Failed handshake with ::ffff:10.0.0.1:42038
Policy Server 12.8SP7 on Linux;
CA Access Gateway (SPS) 12.8SP7 on Linux;
The error "Socket error 97" is returned from the OS, and it means "Address family not supported by protocol".
Usually, this happens as an IPv6 address is requested and the system isn't configured for that.
So, the problem isn't with our product, but with the OS and network configuration.
After having fixed a problem on the Firewall, the issue has been solved.
