Error Text??Transport error: [IPT_HttpSendHttpResponseError] HTTP response error :Unrecognized SSL message, plaintext connection?.

The is an issue with the http vs https url in the connection url :
HTTP, or hypertext transfer protocol, is the way a Web server communicates with browsers like Internet Explorer® and Mozilla Firefox®. HTTP lets visitors view a site and send information back to the Web server.


HTTPS, hypertext transfer protocol secure, is HTTP through a secured connection. Communications through an HTTPS server are encrypted by a secure certificate known as an SSL. The encryption prevents third-parties from eavesdropping on communications to and from the server.


Only servers that have their own SSL can create HTTPS connections.


So if you use https: then use port 443(default port unless its configured for a different port)
If there is no SSL certificate then use HTTP :9090 port configured on the atom( or on your server)


Basically make sure that the urls are correct for the respective port and SSL.
