If you see this message when trying to connect Google Calendar or Stripe Connect to your server, it means that something is blocking latepoint.com from sending data to your site, it might be a security plugin that blocks all requests to /admin-ajax.php or your hosting company. You need to contact them to whitelist POST requests to that url that come from latepoint.com.
You can use a tool like https://reqbin.com/ to check if your server is accepting POST requests to the required URL:
1. Copy the URL from the error notice, insert it in reqbin’s URL field.
2. Set request type to POST
3. Make sure that status is 200 (OK)
