    TIE Reputation - Unable to communicate with Threat Intelligence Exchange server


      Hello all,


      Before upgrading DXL extension and products everything was fine.

      Now in TIE Reputation i see the below error.

      In TIE server topology i have 4 tie servers and now all of them have this error, even if before one of them wasn't having any problems. Ports are opened and servers DXL & TIE are in the same VLAN.

      DXL Connection
      Unable to reach TIE server via DXL.


      ePO is not able to connect to TIE Server.


      Possible cause:

      - No service registered on DXL Fabric for this TIE Server. Check service status on the appliance.
      - No DXL brokers available for connecting ePO and TIE Server. Check connection status of DXL Client for ePO.
      - Verify that DXL Topology settings and DXL Fabric are configured correctly.

      Any ideas what can i do?
