How do I fix it?(error code = 16)

I purchased and installed MATLAB Production Server, then created an Instance and ran it, but the following error came out: "Server failed to start (error code = 16): license checkout failed Server process exited with return code: 16 (check logs for more) information)" Runtime was set in the Setting part of Instance. But I get error code = 16. How do I fix it?

I referenced that url, but I can't understand.

Please refer to This answer by the Mathworks support team.

License error code 16 means MLM daemon path is invalid.

Check your $MPS_INSTALL/etc/license.dat (if Windows, $MPS_INSTALL\etc\license.dat) file and DAEMON MLM path is correct. If you're using Linux, this path would be

DAEMON MLM $MPS_INSTALL/etc/glnxa64/mlm

In case of Windows, this path should be

DAEMON MLM $MPS_INSTALL\etc\win64\mlm.exe
