Today I found an issue on integration between OPM Probe and NFA, we couldn't see any application traffic on Interface GUI of OPM device snapshot. 

     And I made sure that the device has enabled Netflow and we can see the traffic and application of it on NFA GUI. So I navigated to OPM Probe integration setting and re-entered the credential of NFA. Then it gave us error that "Unable to connect NFA server".

    OPM version is 9101 and is deployed with Central-Probe, NFA version is 9600 professional version.

    please give your advice, thx in advance!
