Host Not Resolvable when accessing web via CITRIX Netscaler Webgateway

We have launched six educational sites from our organsiation, These were loading fine during testing.  But today all of them at that same time now get message below.  They work from any other internet access.  But acccesing these six pages throuh a Citrix connection to the web, gives me this message.

(Note that all other website can be accessed via Citrix just fine - just these six can't?  Whats the connection?)

Re: Host Not Resolvable when accessing web via CITRIX Netscaler Webgateway


Hope you are doing well.

Host Not Resolvable:-


This message will be displayed if Web Gateway is unable to contact the DNS server or if the DNS server returns a “No Such Name” response or gives error.


Please refer below link for more information on this:-


Look for Host not resolvable part in above link.
