Can’t generate Domain Key

I installed the plugin but when I try to generate a domain key I get

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://mut-con.co.za/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 have tried a few solutions from searching nothing works. I have 2 subdomains with websites on the same domain and they generated their domain keys.
