Do you get the error when connecting directly to the StoreFront server?
Perform this test by adding the StoreFront base URL and the StoreFront server local IP address to the Hosts file of the internal machine you will be testing with. For more information about editing the Hosts file refer to the following article - How to use a Hosts file to test a site that uses host headers on an Intranet.
Go to the Root Cause table for StoreFront server.
Do you get the error connecting through a load balancer?
Perform this test by opening the command prompt and pinging the StoreFront base URL FQDN. The FQDN should resolve to the IP address of your load balancer. If it does not, then verify your DNS settings or the Hosts file on the local machine.
Go to the Root Cause table for the load balancer.
Do you get the error only when connecting through NetScaler Gateway?
Perform this test by opening the command prompt and pinging the NetScaler Gateway FQDN. The FQDN should resolve to the IP address of your NetScaler Gateway. If it does not, then verify your DNS settings or the Hosts file on the local machine.
