====== Connecting to server KVM console via java ======
If you're having issues connecting to server console because of old java version running on the server via a command like this 

  /usr/lib/jvm/jre1.8.0_361/bin/javaws 'viewer.jnlp(82.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx)'

and you get security warnings regarding certificates or algorithms, there are several options to try.

===== Whitelist the IP =====
Run the

  /usr/lib/jvm/jre1.8.0_361/bin/jcontrol
  
Navigate to //Security// tab and put the https endpoint in //Exception Site List//.

===== Comment out the algorithms =====
Edit the //java.security// file for your java installation e.g ///usr/lib/jvm/jre1.8.0_361/lib/security/java.security// and comment the

  jdk.jar.disabledAlgorithms=
  jdk.tls.disabledAlgorithms=

2 lines.

Try conecting again.
