curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

Redirecting output to ‘wget-log.8’.

Any suggestion please??

About the mechanism of granting permission, I do not talk about it because each one has different requirements (I have to follow if I use it). As for the origin of Litespeed, I didn’t pay close attention, I just knew that it developed based on the strengths of NGINX and Apache. For users, litespeed it simply does not have to configure much. If you need more security, you should probably use paid LSWS Enterprise for peace of mind.
