Critical failure when activating mencached

Good morning, we have a problem every time we activate memcached the web gives us an error that this site has had a critical failure and we have to disable memcached to get back to work with the web.

We put everything right ip, port, user. password.

I do not know if it is an error of your plugin or something, is there any way to use mencached with litesspeed even with another plugin?

Best regards and thanks
