    App visibility agent not working when Java is blocking SSLv3.


    Log files indicate that no handshake is done between agents and server since server is configured to use only secured communication protocols TLS 1.0, 1.1, 1.2 (blocking out SSLv3):

    Step 2) Edit the original file called located in the <installation dir>/ADOP_JRE/lib/security directory 

    Step 3) Find the following line in this file: 


    and remove SSLv3. 

    Step 4) Save the file 

    Step 5) Restart the App Visibility Portal, App Visibility Collector, App Visibility Proxy (if one is installed), and the App Visibility Agents
