Having trouble with the notification server

Hi,

I’ve been trying to set up the notification server. When I start it up, I get the following error for the 22280 port:

[cURL/7] (https://code.sandiamesa.com:22280/) <CURLE_COULDNT_CONNECT> The cURL library raised an error while making a request. You may be able to find more information about this error (error code: 7) on the cURL site: https://curl.haxx.se/libcurl/c/libcurl-errors.html#CURLECOULDNTCONNECT

This happens despite Port 22280 being open and the SSL key and certificate being set up.
