I successfully registered my Citrix license server with Citrix Cloud.
The server side showed online activation successfull, and the server is showing on the cloud side.
Licenses are visible on the server.

My problem is, that after a few minutes the license server seems to lose connection with the cloud.
There is no status of online activation, it just offers the option to register with cloud again.
When I click the refresh button, it ends up in the spinning wheel with grey background.
I tried restarting the various licensing services and even the server, but none worked.

I already removed the cloud registration and started all over again, same behaviour after a bit of time.

This seems very unreliable.
Any suggestions?

Thanks a lot

We are trying to install the latest version of Citrix Licensing that is required for LAS.

The installation is marked as failed although the Citrix Licensing is installed. However the licensing services are disabled (due to failed installation status I guess). We enable the services and notice that the Citrix Web Services for Licensing is unable to start (other services can start).

After some investigation, we found that if we disable the LAS module in the config file C:\Program Files (x86)\Citrix\Licensing\WebServicesForLicensing\Apache\conf\extra\Citrix-SLS.conf, the Citrix Web Services for Licensing is able to start (we put this line in comment: LoadModule ctxlasclient_module modules/mod_ctxlasclient.so).

When we disable the LAS module and start the service, we are then able to connect to the licensing manager console, and we can successfully register the license server with the cloud. However, the server is marked as "not activated" on Citrix Cloud because of the LAS module not being loaded.

On network level all seems OK (no traffic blocked towards the required Citrix resources).

Any idea what is the issue here?

Thank you in advance.

I have a v1912 CU9 environment on Windows 2012 R2 that supports our Dynamics AX 2009 ERP / related applications, which will need to maintain for the foreseeable future. Dynamics doesn't support an OS greater than Windows 2012 R2. We are currently migrating to SAP, but it will not be completed by April 15, 2026. How do I license the legacy (v1912) environment after the deadline?

Regards,

Jeff watts

We would periodically remove stale users eg who have left the business before the 90days default for citrix to delete on license server and wonder can this still be done once move to LAS or is there another option, or do license get freed up any sooner eg daily?

We often find ourselves close to max licensed users and dont want to run the risk of running out. Thanks

Required action

After April 15 2026, any Citrix product which is in scope of this transition and has not been migrated to LAS will be disrupted and will incur an outage. Action to migrate before this date is critical to ensure uninterrupted operation.

The list of products and services in scope for this transition include:

• Citrix Virtual Apps and Desktops including optional components like Citrix Provisioning (PVS) and Workspace Environment Management (WEM)

• NetScaler, including Console and all ADC form factors

• XenServer

• Unicon Scout

• XenMobile

• uberAgent

Three key steps of the process: Upgrade --> Register --> Activate.

Detailed, step-by-step guides for each product are available in the product documentation.

After the April 15, 2026 deadline, support will only be available for LAS compliant deployments. Act now to take advantage of the benefits this update will provide.

For this usage, it consists of:

1. CVAD version 2507

2. License Server version 11.17.2.10 build 53100

3. LAS installed and connected to Citrix Cloud successfully

The problem is that with the new version, license usage cannot be viewed in the old way from Web Studio or Citrix Studio. It only shows Activated data and the next month's expiration date. The License Server also only shows the total number of licenses and expiration date, but no current usage count like in the old version.

After researching further, I understand that it can be viewed at Citrix Cloud > License > Usage. However, when accessing it, it only shows the total count and usage as 0. Even after trying to upload updates from the License Server page multiple times to send the latest data, it remains the same. So, I don't know what the issue is.

I checked with relevant people, and Firewall is set to All open, so it shouldn't be blocked.

What I want to ask is:

1. How can I check usage from Citrix Cloud?

2. How can I know if it's being used up to the purchased amount, since it can't be checked this way?

3. How can I check the logs to verify the actual cause of the problem that occurred?

Thanks.

I have now updated a customer environment to CVAD 2402 CU3 and registered it with LAS.

In Citrix License Manager in the customer environment, it says that the server is registered in the cloud and the online license activation service is running.

But in Citrix Cloud, the server is listed as “not activated.”

I checked the logs and found the following error in “ctxEventsCasUploader.log”:

“Cloud registration check failed with retCode = 5.”

Could this be related? Everything should be fine on the firewall side.

Investigating migration path to LAS.

With file based licensing we use same license file for test and production environments. We use same hostname in both environments so there is no issue.
Can we use multiple license servers with LAS?

Kind regards,

Bart.

Does it still use port 27000 as before, or has it changed to a different method?

The reason I’m asking is that I already have a License Server configured with LAS, and we have two sites sharing the same License Server.

Do we still need to open the same ports as with the old License Server, or not?

If not, please advise what kind of communication setup is required.

Is this correct?
