If you go this error it’s probably because something is missing in the configuration on the NetScaler side.
Here are some explanations:
When you edit your XenMobileGateway you should have this:
3 session Policies

- In the configuration utility, on the Configuration tab, expand and then clickClientless Access.
- In the details pane, on the Policies tab, click Add.
- In Name, type a name for the policy.
- Under Expression, type HTTP.REQ.HEADER(“User-Agent”).CONTAINS(“CitrixReceiver”) && HTTP.REQ.HEADER(“X-Citrix-Gateway”).EXISTS .
- Next to Profile, click New.
- In Name, type a name for the profile.
Important: Do not change any settings in the profile.
- Click Create two times and then click Close.
