Unable to connect rstudio server on Redhat server

rstudioserver

#1

I have a Redhat server installed on a VM.
I have installed Microsoft open R. verified it works through ssh session
Installed and verified rstudio server setup

Now I'm trying to access the rstudio server through browser and cannot connect.
I made sure we are on the same network.
"netstat -plnt" shows that port 8787 is listening to rserver program.

Any tips on how to further investigate?
Is this a networking mode issue for the VM?
