Why do I receive "error code 16" when I try to start MATLAB Production Server (MPS) using mps-start?

I created a new instance of MATLAB Production Server (MPS), but I cannot start it.

When I run the command mps-start, I receive the following error:

ERROR: Server failed to start (error code = 16):  license checkout failed
Server process exited with return code: 16
(check logs for more information)

How can I resolve this issue and start the MPS instance?

"Error code 16" indicates one of the following issues:

• The network license manager is not running
• The license file and/or license server cannot be located
• Ports between the Network License Manager and MATLAB Production Server are blocked

To resolve this issue, you must specify the license files and/or license servers by editing the following configuration file:

$MPSinstance\config\main_conf

(where $MPSinstance is the folder that contains the MPS instance.)

To edit the configuration file:

- Go to the folder containing the MPS instance.

- Go to the folder "config".

- Open the file "main_config" in a text editor.

- Locate the section "License Management Settings".

- Locate the following line:

# --license

- Uncomment the line:

--license

- Add colon-separated list of license file(s) and/or license server(s):

--license C:\MPS\licenses\network.lic
--license 27000@mps-license-server

(NOTE: The absolute path must be used for license files.)

- Save the file "main_config".

You should now be able to start the MPS instance.

What is the error message? Could you provide the log file?

The log is located in your_MPS_instance\log\main.log
