Domain key issue facing

#1
Hey,
I installed the Litespeed cache plugin and when I tried to apply for the domain key it is showing the following error:
Notice:
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://kanzolquran.com/wp-json/litespeed/v1/token 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.:



I already set all the settings from the security


How can I get rid of this error?
