Hi @Piraisudan Rajendran,
You are receiving the error log ‘Failed to start with error, code = 16, message = license checkout failed’. You can leverage the following MATLAB answer to diagnose the issue:
https://www.mathworks.com/matlabcentral/answers/106144-why-do-i-receive-error-code-16-when-i-try-to-start-matlab-production-server-mps-using-mps-start
License error code 16 could also mean that the 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
Hope this will help!
