Hi @vijayrcse,

Are you exposing your Selenium Grid publicly on AWS? I guess you need to double check your networking rules and everything related to the exposed ports...

But more importantly, if you are exposing the Grid, it wouldn't be a good idea, check these two issues:
SeleniumHQ/selenium#2076 and #147

No , its not aabout Selenium grid publicy on AWS. I have my hub and node docker container running in ec2 instance( Amazon llinux). I have trying to use the vncviewer command from ./bin/vnvviewer.
I downloaded the vnc viewer binary from realvnc and placed in path

But when i start the vncviwer from my amazon linux ec2 instance , connectting to the port where vnc server is exposed by node image, it could not connect. Getting the below error

I am looking for clear instruction of running the vncviewer from linux machine sso i can connect to the 5900 port. Current documentation is not helping. Please advise
