Other optional information you want to add other than the above:

Ip blacklist/whitelist works fine, after you have added ips into the table you need to restart webserver (no reload, but restart).

Why would you restart vs reload?

Reload doesn't reload script it reloads only nginx config / openresty config. In my openresty reload doesn't work for script but restart re-reads it and blacklist/whitelist works as expected.

Sounds like something is being done wrong if that's what you're getting IMO. A reload should do just that, gracefully reload the config openresty/nginx config, re-init_by_lua, etc

The

Ip blacklist/whitelist works fine, after you have added ips into the table you need to restart webserver (no reload, but restart).

If you you put to many ranges like 15 ranges of IPS it doesn't works ! If i put less ranges like 5 it works !

Actually i have 43 ranges whitelisted to be exact :-)
