Wordpress LScache Plugin: Problem Retrieving Domain Key (trying to connect to QUIC CDN)
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi there, Ive recently set up my server to use Litespeed and set up the Litespeed Cache on my site. Now Im looking to start using the QUIC CDN, but Im getting the following error when trying to get a domain key: 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://plantingjustice.org/wp-json/litespeed/v1/token failed. 2) Our Current Online Server IPs was not whitelisted. Please verify that your other plugins are not blocking REST API calls, whitelist our server IPs, or contact your server admin for assistance.: My security plugin is Astra (getastra.com), and Ive whitelisted all of the server IPs there. Not really sure what to do here, any help is appreciated. Thanks, Gabriel Update, 5:10 pm EST: My Astra Security Hardening plugin had WP API JSON disabled. Ive reenabled it, and am waiting to see what happens. This topic was modified 1 year, 10 months ago by pristineorigins. Reason: Status update The page I need help with: https://plantingjustice.org Hi, I am still seeing 403 and 401 error on REST URIs make sure you access https://plantingjustice.org/wp-json/litespeed/v1/token , and see things like _res : ok Best regards, Hey, Thanks for the fast response. Im seeing _res : ok on that page now. What should I do about the 403 and 401 errors on the REST urls? Not sure if this is relevant, but my site is running on a Litespeed server with the Litespeed Cache plugin configured. okay, please try refresh the domain key again I will check the log Done, just sent it in. Thank you! I am seeing sucess from my side how about your side ? Looks like it worked. Thanks so much! Question, if I disabled the WP API JSON in my Astra security hardening plugin again, this would probably stop working, right? It needs the JSON API to work? Hi, yes , online services like image optimization , LQIP , CCSS ?etc , requires WP API Best regards, Okay great, thanks a lot for the help, I really appreciate it. Best, Gabriel my pleasure
