  • 1.  Intermittent connection of hub to tunnel

    Posted Aug 19, 2019 07:02 PM
    Hi,

    I'm having issues with hub to hub connection via Tunnel. There are times that the Queue would drop and be unconnected and there are times that the Queues are fine and communicating well. I also see this kind of logs from hub probe of the secondary hub:

    hub: TSESS could not connect to tunnel
    hub: CTRL <Primary Hub> could not connect to server
    hub: ssl_connect - connect to '<Primary Hub IP>' failed (110)
    hub: hubup - send failed for <PrimaryHub:Port> communication error
    hub: TSESS-P-5416 SSL_shutdown failed
    hub: Error shutting down SSL connection
    hub: TSESS-P-5418 SSL_shutdown failed

    Also, there are logs from other probes that has license expired errors:

    Controller: Probe 'interface_traffic' FAILED to start, the license has expired
    Controller: Probe 'net_connect' FAILED to start, the license has expired
    Controller: Probe 'snmptd' FAILED to start, the license has expired
    Controller: Probe 'cisco_monitor' FAILED to start, the license has expired
    Controller: fopen failed for probes/service/discovery_agent/bulkping
    Controller: port_unregister: Unregistration of net_connect failed

    Should create a fresh new tunnel connection between Secondary to the Primary hub? Or is there any solution for this kind of problems? Thanks

    Try upgrading hubs to the latest version and applying the following KB:

    Article title: hub and tunnel connection settings in 7.x and 8.x

    both hub & robot should be the latest
    you will need to get new licenses to resolve the license has expired problem.
