RStudio Server Community Edition - Initialization Error

I upgraded RStudio server community edition to the latest version and now I am not able to access RStudio through localhost:8787. It was working before the update. I am using Scientific Linux 6.10

I keep getting a "RStudio Initialization Error - Unable to Connect to Service" Error.

When I run the 'RStudio-server verify-installation' command I do not get anything in return which I think it means the installation is fine.

When I check /var/logs/messages, I only see "Nov 14 15:23:29 localhost init: rstudio-server main process (3423) killed by TERM signal" and that happens because I stop and then start the server.

I'm not sure what else to check... please advice.

Thank you.
