[BUG] “Unexpected Response” Access Gateway Enterprise in NetScaler build 9.3-53.5

If you are using Citrix Receiver on iOS or Android to access pulished applications on Citrix Access Gateway Enterprise (NetScaler) do not upgrade to the latest firmware which is 9.3-53.5.

Users will get an “Unexpected Response” on an iOS device when they try to login to a Citrix Access Gateway environment. On Android the error statement is “The Citrix Access Gateway you are connecting to is not configured for this device. Please contact your administrator."

On the Citrix Forum there is a post where more users are reporting this issue: http://forums.citrix.com/thread.jspa?threadID=297625

Citrix is aware of the issue and are working on it.

Update: Problem is resolved as of build 9.3-54.4 or newer.
