Why am I unable to access the GUI after installing Splunk?

Hi Team,

I am unable to access the GUI after installation is done on the Splunk PROD server.

I tried with IP Address, FQDN, Hostname but not working. It's getting worked with the TEST Servers but not with PROD servers.

Getting this error when I tried to access the GUI.

Time-outs often are caused by firewalls.  Verify any firewalls in your network are allowing connections from your workstation to your Search Head's port 8000.

Thanks @richgalloway

 I tried with the double tunneling then it got worked out. 

Now Iam able to access the GUI of all servers.
