This error means the port is already in use by another program. To resolve this, you will need to change the port number listed in the license file on the network license manager. The license manager software can automatically choose a free port if you remove the port number from the server line in the license file. For more information about changing the port number in the license file, see the related solution: 1-19C0V - "What ports does the MATLAB network license manager use, and how can I set those ports?"
