STA server status is Down on Gateway vserver though it is reachable from the NetScaler
The hostname should not have extra characters
For Example:
set ns hostName "CTXNETSCALER"
In the 14.1 release, a new functionality was added for DDC monitoring. Header "Citrix-UserAgent" is included in http POST request.
This Citrix-UserAgent header value is in format "Gateway/NS_Version/NS_Hostname/NS_IP". If the hostname contains extra character, the value is wrapped in the next line. Hence it will receive a "400 Bad Request" response
For Example:
set ns hostName "CTXNETSCALER\r"
