Wordpress LScache Plugin: Another Problem Retrieving Domain Key (trying to connect to QUIC CDN)
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, another user with Domain Key issues. There was a problem with retrieving your Domain Key. Please click the Waiting for Approval button to retry. There are two reasons why we might not be able to communicate with your domain:: 1) The POST callback to https://wojtek.jakobczyk.org/wp-json/litespeed/v1/token failed. Doesnt work even if I disable all security on the site. The token is there. Any chance for some debugging on your side? The page I need help with: https://wojtek.jakobczyk.org/ Hi, you have something blocking WP REST https://wojtek.jakobczyk.org/?rest_route=/litespeed/v1/token you can see it shows a HTML page, instead of JSON response it should respond as this page shows Best regards, Using: https://wojtek.jakobczyk.org/wp-json/litespeed/v1/ip_validate The response is: code : rest_no_route , message : Nie znaleziono routingu pasuj u0105cego do adresu URL oraz metody zapytania. , data : status :404 which is in line with the troubleshooting page. I went that far I disabled all plugins on the page apart from LiteSpeed. Removed absolutely everything apart from https redirect from my .htaccess and let LSCache write its data into it again. Still no go. Reason: (added .htaccess edit) Hi, yes, sorry , the FAQ is out-dated, we will update, but it is actually using the link on https://wojtek.jakobczyk.org/?rest_route=/litespeed/v1/token you need to make this link works as your https://wojtek.jakobczyk.org/wp-json/litespeed/v1/ip_validate first , then request the domain key Best regards, Hi, Im going to mark this topic Resolved , due to lack of activity. If you still need help, please feel free to re-open it. When re-open it, please also change the topic status to not solved Best regards, Reopening, as still no go with Litespeed Cache. The result of calling https://wojtek.jakobczyk.org/wp-json/litespeed/v1/token is: _res : ok Still, I disabled WP Cerber Security, there is no trace of anything that could be blocking API calls in wp-config.php as well. While I am behind cloudflare, all the IPs are bundled into an allow rule in CF firewall. CF reports No firewall events found matching your filters anyway. I do however have a few API calls saved in REST API LOG plugin: Date: 2021-03-12 00:51:43 Source: WP REST API Method: POST Status: 200 Elapsed Time: 1,443ms Response Length: 150 User: IP Address: 188.68.46.236 Request headers: accept : / , content_type : application /x-www-form-urlencoded , content_length : 4 , host : wojtek.jakobczyk.org , user_agent : curl /7.29.0 Response headers: Content-Type : application /json charset=UTF-8 , X-Robots-Tag : noindex , Link : rel=https / /api.w.org / , X-Content-Type-Options : nosniff , Access-Control-Expose-Headers : X-WP-Total, X-WP-TotalPages, Link , Allow : POST, GET , Access-Control-Allow-Headers : X-WP-Nonce Response body: data : _res : err , _msg : lack_of_param headers : Allow : POST, GET status : 200 Hi, sorry for the confusing , the REST URL should be like this https://wojtek.jakobczyk.org/?rest_route=/litespeed/v1/token Best regards, OK. It displays a HTML page indeed. Where in WordPress should I look to try and solve this issue? Apparently it is still something in my configuration. Hi, frankly I dont know , there are millions ways to disable this my best guess is plugin , you can try disable all other non-essential ones first and see how it goes besides wp-config.php , themes functions.php could also be used for disable WP REST if you did add some code into it before Best regards,
