Most of you would already be aware of the "Connect using VMRC" option for a Virtual Machine through the vRealize Automation Self Service Console.
Its one of the most commonly used feature and i have never faced any challenges with it up until one of my customers complaint that they are getting a Black black screen while connecting with VMRC.
I immediately started thinking it towards a port problem.
VMRC through vRA uses TCP port 8444 from endpoint browser to VRA. So we tried a telnet and it worked...hence it wasn't a port issue.
