Since yesterday, every 30 mins, I am receiving an email with this text:
"Warning: fsockopen(): unable to connect to node5.quic.cloud:443 (Connection timed out) in /home/xxx/public_html/domain.com/wp-content/plugins/litespeed-cache/src/utility.cls.php on line 169"
Together, in the “LiteSpeed Cache General Settings” page I see:
There was a problem with retrieving your Domain Key. Please click the Waiting for Refresh button to retry. There are two reasons why we might not be able to communicate with your domain:: 1) The POST callback to https://www.domain.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.:
Please explain, what am I supposed to do, I don’t know anything about “POST callback” oe “allowlisted”.
