I have setup a replica of our live site on our inhouse server to try and resolve our session recording issues. So we can record sessions see how it sworking. I am using the www2 prefix for this. I am getting this error in system check
Requesting ‘https://www2.abc.com/analytics/plugins/HeatmapSessionRecording/configs.php?idsite=1&trackerid=5lX6EM&url=http%3A%2F%2Ftest.test%2F’ resulted in an error: curl_exec: failed to connect to www2.abc.com port 443: connection refused. hostname requested was: www2.abc.com. As a result, tracking Heatmaps and Session Recordings may not work. You may need to change your webserver configuration to allow access to this file via the Internet or Intranet.
What is trying to access port 443 ? The site is being served ok on https. It is behind a nginx proxy. Niginx listens on https but site is running on http.
