    Unable to connect to EMS on Win7

    Anybody see the obvious in what I am missing here?


    I start WSEMS on my Windows 7 machine with loglevel turned on to VERBOSE


    It uses the following config.json (sensitive fields xxxxx’ed) and the websocket connects and is open up to the cloud platform.



                    "ws_servers":     [{

                                                  "host":  "xxxxx.cloud.thingworx.com",

                                                  "port":   443


                    "ws_connection":             {

                                   "encryption":      "ssl",

                                   "verbose":           true


                    "certificates":     {

                                   "validate":           false


                    "appKey":            "xxxx-xxxxxx-xxxxxxxx"





    When I try to address the EMS from browser on the same machine as the EMS https://localhost:8000/ThingWorx/Things


    Connection is refused and I see the following in the wsems trace:



    [AUDIT] 2015-12-10 15:04:36,580 SDK: twWs_Connect: Websocket connected!     <<-- Next two lines show the websocket connected (EMS is running)

        Beck, under the certificates section, try adding the 'allow self signed' certificates section. Here is an example snippet:


        "certificates":  {

                                "validate":       false,

                                "allow_self_signed": true

          The connection settings for the websocket (which connects to the ThingWorx server) and the REST API are separate.  The REST API defaults to listening on localhost:8000 as you are using, but it defaults to HTTP not HTTPS.  You can enable HTTPS in config.json.  Look at the "http_server" section.
