App service HTTPS random errors

Question

We have an app service that works well for a few months now.
For a few hours, we have random errors (1 error for 5 success approximatively) when we try to call it with an HTTPS connection. It works well with an HTTP connection.
We have not any error log. Curl returns CURLE_SSL_CONNECT_ERROR.
I hope I will find help here!

Thanks for asking question! You can inspect the log files from the browser at https://<app-name>.scm.azurewebsites.net/api/logs/docker for more details on this.

You may check if CURLOPT_SSL_VERIFYPEER option is enabled. As when making request with using cURL from PHP code regular http:// calls everything, but for https:// you need to configure few things on App Service manually for it to work correctly.
