Unable to access Storefront through NetScaler Gateway and getting ” Could reach the page ” error.

– After upgrading to 12.0 build 58.15 , unable to access the Storefront server through NetScaler Gateway and getting ” Could reach the page ” error.

NOTE: On NetScaler Gateway Session profile, the Storefront URL is configured with Storefront Load balancing server IP.

– If Storefront Load balancer IP is replaced with Actual Storefront Server IP, then Storefront is accessible through NetScaler gateway.

In the following nstrace screenshot, we could see that the Storefront Load balancer has sent Export cipher in the Server Hello. For which, we could see a FATAL Error message from NetScaler gateway Vserver.

Which timezone’s time NetScaler supported default : Standard / Daylight

Working of Time Zone :

In NetScaler configuration we only need to select time zone which so ever listed.

In older builds you will find Standard time zone & in newer build you will find Day light saving time.

All time data handled by NTP is in UTC. Your local time zone [ NetScaler Selected Time zone ] setting determines the offset from there.

NTP does not recognize time zones, instead it manages all time information’s based on UTC.

You just need to apply the available time zone settings in your NetScaler and as per the UTC time provided by NTP it will get changed +1 , -1 hours.

Example : Australia [ Melbourne ] , which have Standard time as +10:00 AEST and daylight time as +11:00 AEDT.

NS 10.5 Standard Time AEST +10:00

NetScaler Gateway Error: “The published resource is not available currently”

The error is displayed when we access the WI url configured with Secure Gateway. Create a Direct site and it should work fine.

This issue is most likely related to compatibility between Secure Gateway 3.3.0 and Windows Update.

Error: “Your apps are not available at this time. Please try again” When Receiver Connects Through NetScaler Gateway

Solution 1

To resolve this issue change the beacon entries in StoreFront. Add the NetScaler Gateway addresses to external beacon.

Reference: https://docs.citrix.com/en-us/storefront/3-11/integrate-with-netscaler-and-netscaler-gateway/configure-beacon.html

External Beacon

If you want to use ICA proxy from internal and external connections (all clients should only go through NetScaler), then add a fake address in the internal beacon of StoreFront.

Note: The internal beacon should only be resolvable inside the network, if the beacon is resolvable externally then Citrix Receiver will not be able to add the account.

Solution 2

The issue relates to compatibility of Receiver 4.x and Web Interface XenApp services site. Receiver 4.x supports services sites but when connecting thru NS, users may experience issues as described in CTX136828 – Error When Using Windows Receiver PNAgent through Access Gateway Enterprise Edition Appliance.

Also note Citrix Documentation – NetScaler to Web Interface XenApp Services site is not supported.

Netscaler VPX 1000 – Azure – Slowness getting through Netscaler.


With 12.0 builds, we have changed default yield behavior for PE vCPUs. vCPU will not yield to hypervisor, even though if there is less/moderate traffic in 12.0 build, which was not the case for 11.1 builds. That’s the reason, VPX vCPU is always 100% on hypervisor. However, vCPU is allocated to management core might not be 100%.

NetScaler yields PE vCPUs to hypervisor in sparse/moderate traffic cases. Since we have observed Tx overflow/congestion, it’s somewhat related to scheduling, we thought not yielding vCPU helps in improving the situation.

– set ns vpxparam -cpuyield NO

Upgrade to 12.0.53.X+
