please add this code to your theme’s functions.php

function ip_check_callback() {
    $data = array(
        'remote_ip'         => $_SERVER['REMOTE_ADDR'] ?? 'Null',
        'x_forwarded_for'   => $_SERVER['HTTP_X_FORWARDED_FOR'] ?? 'Null',
        'proxy_remote_addr' => $_SERVER['PROXY_REMOTE_ADDR'] ?? 'Null'
    );
    
    return rest_ensure_response($data);
}

function register_ip_check_route() {
    register_rest_route('lscwp', '/ip-check', array(
        'methods'  => 'GET',
        'callback' => 'ip_check_callback'
    ));
}

add_action('rest_api_init', 'register_ip_check_route');

this code will create an API endpoint for us to check

please let us know when you have done it

your domain is giving me 500 error ? please verify

please remove above code

then go to LiteSpeed Cache -> toolbox -> debug setting, set debug log to ON, debug level to adanvce , debug include URI, put rest_route=/litespeed

then go to toolbox -> log view -> clean up existing log if any

then try to connect again

if it still fails, go to log view again , copy paste and share log via https://pastebin.ubuntu.com/

log please?

I just send a request to it , do you see the log ?

add litespeed_type=activate into the debug include URI, alone with previous URL

and try activate QC service again , see if it generates any log

and please clean up existing log

no , i mean , try to enable the qc service again , in litespeed cache -> general page

you have weird case

please create a ticket by mail to support at litespeedtech.com with reference link to this topic , we will investigate further
