[SOLVED] Cannot access RA from RM desktop

needexpert

Hello,


  We are in the process of evaluating RM/RA as potential solution for our data mining needs.  I've set up RM locally and two instances of RA, 1 on a emazon EC2 instance.
and 1 locally on a mac

   On my local version of RA everything works as intended when interfacing between RA and RM.
   
   I run into an issue when attempting to access RA within the amazon instance. When trying to connect via RM -> RA I get the error message. "operation timed out".
If I try to use the .gnlp file to connect RA -> RM - I get an error stating "Unable to launch application".   I've pasted the results of the "More Information window below"


Hopefully someone has experience this before and found a solution.


    I apologize if this question redundant. I've been taking advantage of the forum when setting up my tests but could not find the answer for this problem.

thanks in advance
