Hi Phil,
Thanks for the quick reply.

I now have the Mango login screen displaying on the cloud server. I resolved this by creating a firewall rule to allow traffic through to port 8080 (so effectively port forward). I may need to change to port 80 to lose the port from the URL in the future- thanks for that tip! The echo $JAVA_HOME. I did log out of ssh session so I think it should work. I need to look into this further but the issue right now may be my lack of linux use. I may need to add JAVA_HOME to the profile file instead. The java.net.UnknownHostException message at the stack trace- I got this message prior to creating the firewall rule so I need to check for this message when I restart Mango (I can only do this next week so I will keep you posted)
Great software and great support- much appreciated
Paul
