Unable to launch RStudio Server

Hello everyone,

I hope someone could help me out with an issue that am facing. I have successfully installed R + RStudio Server in an RHEL 7.0+ EC2 machine. Unfortunately, I am unable to access the server. I am not particularly sure what is going on here. Below are some of my findings:

  1. Running netstat -lntp shows that RServer is running on the right port.
netstat -lntp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0  *               LISTEN      1169/master
tcp        0      0  *               LISTEN      27527/rserver
  1. Running rstudio-server status shows that the server is active with no issues.

Sep 28 17:58:57 PTAWSG-1RPHap01 systemd[1]: Started RStudio Server.
  1. Running rstudio-server verify-installation yields no results. This seems to be an unexpected behaviour?

  2. Looking for the Rserver process ps -aux | grep 'rserver' yields:

rstudio+  1976  0.3  0.0 147480  3456 ?        Ssl  14:29   0:00 /usr/lib/rstudio-server/bin/rserver

  1. Hitting URL = gets me a Network error : 503 code (tcp_error)

Please advise. Appreciate any help I can get.
