How to troubleshoot your network license setup

2017-03-08

Depending on your environment, you might experience issues with the XLSTAT Network license server. This guide will help you on troubleshooting your installation. If you are looking for details on how to perform a proper installation in the first place, please refer to the corresponding guide by clicking here.

When clients cannot communicate with your server

The XLSTAT clients require to communicate with the server in order to retrieve its usage rights. This is done over the TCP protocol, on the port 7070 by default.

If you happen to experience problems when opening your XLSTAT clients, it might be because this connection cannot be established. This would cause the following message to appear:

XLSTAT cannot communicate with the server error
Figure 1. Failed to communicate with the server.

In this case, please make sure of the following:

  • If you changed the default port, 7070, on the license server, make sure to make then change on the clients as well, so they know how to contact the server,
     
  • The Windows firewall blocks inbound connections by default. The TCP port 7070, or the one you set the server to listen on, should be allowed on the Firewall of the machine.
     
  • If you are in a large corporate network, it is likely that your server is in a different subnetwork as your client’s. In this case, the connection on port 7070 should be allowed on the firewalls that restrict the communications in between those subnetworks.

When the server cannot process requests from clients

When starting an XLSTAT client, you might come into XLSTAT starting with the Free Version. This could happen if the server was not able to process your request. This problem could also cause an error 34 to appear.

In this case, please make sure of the following:

  • That you activated a proper network license on your license server. To find out if your activation was successful, please execute the script XLSTAT-Server-ShowUsage.bat. It is located in the installation directory of your license server. It should display features as shown in figure 3. If you do not see any feature, please activate your license server using a network license key. This is described in the activation part of the Installing XLSTAT Server with the XLSTAT Network Concurrent License guide.

  • That your server is not suspended. This can be checked from a terminal on your license server. Using the cd command, navigate to the server folder in the installation directory of the XLSTAT Network license server. Run this command:
    admin.bat -server localhost:7070 -status -resume
