Problem with receiving domain key

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://abcd.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.:

After this I have make CF security to low & bot fight which is already disabled.

Again when I tried to received domain key then again this same error arise
