Unable to activate a license due to Error 51404 (typically when using Windows Server 2012)

Symptoms

License fails to activate and returns the following error message:

 

Error 51404 = flxActTransactionSend: GEN: Failed to send request. Unable to connect to server https://licensing.hexagongeospatial.com:443/flexnet/services/ActivationService?wsdl

 

Diagnosis

In order to successfully activate a license, the client system must have TLS 1.2 enabled and be able to connect to the URL: https://licensing.hexagongeospatial.com:443/flexnet/services/ActivationService?wsdl 

 

Note that the Windows Server 2012 operating system does not have TLS 1.2 enabled by default so the license activation "Error 51404" failure is most often observed with that operating system, but it can occur for other operating systems as well.

 

 

Solution

To enable TLS 1.2 open 'Control Panel' and select 'Internet Options', then under the Advanced tab scroll down to the Security section and check the “Use TLS 1.2” option. Click OK to save the settings.

The license can fail to activate with the same message if the most recent Windows Updates are not installed for the computer or if the Firewall settings are blocking access to the internet via port 443.  Therefore if enabling the 'Use TLS 1.2' option does not resolve the problem, ensure that the latest Windows Updates are installed and check to see that the Firewall is allowing internet traffic via port 443.

 

To see if you have network access to the license activation server, you can peform the following tests...

 

  • Try to ping the license activation server by opening a Command Prompt window and entering the command line...

ping licensing.hexagongeospatial.com

 

If the ping request is unsuccessful this indicates that your network is unable to communicate with the license activation server.

 

This should return an xml document. If an error is returned by Internet Explorer when connecting to the URL this indicates that access to the license activation server is likely being blocked by a firewall setting or there is no internet access from that system.

 

If the security settings at your site prevent connecting to the internet, then the use of Activation ID based licenses that require internet activation will not be possible. In that you will need to use an offline license instead. An offline license uses a certificate based license (.lic file) that does not require an internet connection.  Instructions for creating an offline license can be found in the Knowledge Base article:  How to claim an offline 2018 license from the Licensing Portal?

Dear all,

what about Windows Server 2016?

In the Release Guide of the Geospatial Licensing it is not mentioned. Is Windows Server 2016 supported?

 

Another question. 

If I install the new license manager on a server, has the server to be always connected to the web or only in the activaction phase (when I write the activation ID and click on ACTIVATE).

 

Thank you very much

I have installed it on Windows 2016 Server without any problems.

I believe Licensing only needs a connection to the Web for the Activation phase.

I had the same "Unable to connect to server" issue on Windows Server 2008 R2. After I disabled Internet Explorer Enhanced Security Configuration it was possible to activate the license.

 

However, the licenses were not avaialbe to use. After a system restart, the License Administrator couldn't start the license service. Then I checked the lic files at the C:\Users\Public\Intergraph\Licenses folder. the lic name was EMPTY_SERVER{xxxxxx}.lic and it's contes were only :

 

SERVER LICENCAS 497905A28E97
VENDOR INGRTS
USE_SERVER

 

The license files was empty...

 

I've tried to deactivate and reactivate the licenses without success.

 

Decided to remove and reinstall the License Administrator and now I just can't run it because it crashes right after initialization.

The partial (empty) .lic file that you describe is normal for license activation.

 

The activation problems need to be handled through the Support Ticket. Maybe some good advice will come from this forum.

 

It's possible that Microsoft .Net Framework has been compromised after removal and reinstallation of the Geospatial Licensing Administrator. This will prevent the License Administrator from running. The .Net Framework problem has only been observed with .Net Framework version 4.6+.

 

Repair .Net Framework, then retry running the Geospatial Licensing Administrator again. Repairing .Net Framework is relatively easy for Windows Server 2008 R2 from the Windows Programs and Features list.

 

Kind Regards,
