Connection Cache add failed
We are having MPLS connectivity between branch and HO firewall. We are trying to access out finsso application which is hosted behind HO firewall over the MPLS connectivity. But that application is not accessible and if I see in packet capture I am getting "Drop Code: 254(Connection Cache Add Failed), Module Id: 25(network), (Ref.Id: _3450_uyHtJcpfngKrRmv) 1:1".
Please find below screenshot of packet capture.
