Issue: 

After the network license server is deployed, a client may show the message:“No license available on the server. Please check the server and port settings, then query again.” How can this be resolved?

Solution:

  1. The issue is usually caused by port conflicts. Click the Config button in the server's Network License Manager to check if the port is occupied.
  2. If the port is occupied, change it to any port between 27000 and 27009. Save the settings, then restart the ZWSOFT License Manager.


  3. On the client, enter the new port number (such as 27001) and retrieve the license again. The client will be activated successfully.
