Sysadmin Stress Test ApacheBench

Hi everyone,
I would like to subject my site with wordpress to a stress test
The site is hosted on my virtual server with hyper-v, entirely dedicated to centminimod
While I have no problem stressing, on another server, for the centminimod server I cannot start the test
I also disabled CSF
For stress use:
Server with centminimod:
