Domain key

(the below error occurs when i try to connect Litespeed Cache/ to my wordpress website)
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 failed.

2) Our Current Online Server IPs was not allowlisted.

Please verify that your other plugins are not blocking REST API calls, allowlist our server IPs, or contact your server admin for assistance.:

My site is very slow. Please help

(other information and details relevant to your question)

Reduce the number of plugins. Or upgrade to premium hosting

Likely due to this?


We don’t have Litespeed servers, so I’m not sure if you can use Litespeed cache with us. I’ve been told that Litespeed cache works pretty well if you have Litespeed servers, but for general purpose caching plugins better options exist.

Our servers block REST API calls, so this may not work.

If you want caching and CDN, we see many people have better success with Cloudflare and a regular WordPress caching plugin, like W3 Total Cache or WP Super Cache.
