5. Error: Your server is blocking outgoing HTTPS calls:  You can ask your webhosting provider to execute the below command on the server console:

$ curl -vvv
* Rebuilt URL to:
*   Trying
* Connected to ( port 443 (#0)
* ....
* ....
* ALPN, server did not agree to a protocol
> GET / HTTP/1.1
> Host:
> User-Agent: curl/7.47.0
> Accept: */*
< HTTP/1.1 200 OK

If its working and you get 200 OK, everything is working as expected and problem lies elsewhere. If not, ask your webhosting provider to unblock it, so that the call goes through.
