Summary

When you launch your Esko software, you get the following error:

"We can't connect to your license server. Please verify whether the license server is running and recheck."

Solution

To troubleshoot this issue, proceed as follows:

  1. Check if the Network License Manager is up and running.
    If no problems with the Network License Manager can be found, proceed to the next step.
  2. Check the connection from your computer to the Network License Manager.


To check the Network License Manager:

StepAction
1Go to the computer where the Network License Manager is installed, login and launch the Esko Network License Manager.
2

Take note of what happens when you launch the Esko Network License Manager, and:


To check the connection from your computer to the Network License Manager:

StepAction
1Go to your the computer where the application is installed.
2

Check if the computer name is known and if there is connection issue to License server Flexera License Manager:

  1. On Mac, Spotlight Search - Terminal, press Enter and in new window:

    1. Type the command nslookup <server>. If the command returns an error indicating "Can't find <server>", check the error with your network administrator.
    2. Type the command telnet <server> 27000. If there is error, check the error with your network administrator. If the network administrator is not available and the network is not properly setup, you can try using the IP-address instead of the computer name. You can use these directions explained here:


  2. On Windows, Start > type cmd, press Enter and in new command window:

    1. Type the command nslookup <server>. If the command returns an error indicating "can't find <server>", check the error with your network administrator.
    2. Type the command telnet <server> 27000.  If there is error, check the error with your network administrator.

      If the telnet command not available you may have to Enable telnet.
  3. Check the results of the telnet command.

    Note 1

    If the telnet command returns error indicating 'connect failed' or 'refused', retest again with portnumber  in rang of 27001 to 27009, until the command reports 'Connected'.

    Note 2

    If all telnet commands return refused, the Network License Manager may be configured to use different network port, or there may be a firewall blocking communication between the Network License Manager server computer and the computer. Ask your network administrator. This article explains how to find out. If the server has been setup to use a different port, use that value of the port in the <telnet> command and check for errors.
  4. If the telnet command reports no error, proceed to step 2.b.
3

Check if there is a connection issue to the License server Esko daemon.

The Esko application also needs access to the Esko daemon, running on the Esko Network License Manager computer. In this step we check if the application can connect to that daemon and the appropriate port.

Look up the port being used by the Esko daemon and check access it:

  1. On Mac > Spotlight, Search - Terminal, press Enter and in new window:

    1. Type the command: grep "Listening port" /Library/Application Support/FLEXnet Publisher/Manager/Log File/flexlm.log
      The command will return something similar to:
      13:27:57 (esko) (@esko-SLOG@) Listening port: 62120
    2. Type the command telnet <server> <Listening port>.  If there is error, check the error with your network administrator.

  2. On Windows, Start > type cmd, press Enter and in new command window:

    1. Type the command: findstr /C:"Listening port" c:\Esko\bg_data_system_v010\flexlm.log
      The command will return something similar to:
      13:27:57 (esko) (@esko-SLOG@) Listening port: 62132
    2. type the command "telnet <server> <Listening port>".  If there is error, check the error with your network administrator.

  3. If the above does not help, retrieve the actual error for checking a license on the Network License Manager.

    1. Launch the Esko Local License Manager. Hit the F4 key. The Feature Key dialog will popup.
    2. Enter a query similar to this in the Edit field, and click OK button. cusid 1.0 @server. A response dialog will popup with a full error description in a column called Error Info. Check the error string with your network administrator.

  4. If the above does not help, please contact Esko Support and provide a screenshot of the error which you retrieved in the last check (step 3.b).
