Raspberry Pi Tutorial - Failing to make connection to Thingworx

When attempting to update the Thing humidity and temperature properties in Thingworx the python program is failing to make a new connection. The following error occurs.

 

HTTPSConnectionPool(host='thing-server-qa.rd1.thingworx.io', port=8443): Max retries exceeded with url: /Thingworx/Things/RaspberryPi1(5305843aa530edef)/Properties/*?verify=False (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x75f5e830>: Failed to establish a new connection: [Errno 110] Connection timed out',))

 

I have used Postman to test the HTTP put command for the REST API and obtain a status of 200 OK so I know the information being sent to Thingworx server is correct. However, even then the property values are not being updated. For the python program I have verified that the Thing name and app key are correct.

 

So I believe this may point to two issues:

  • Issue with python program establishing connection to Thingworx server
    • Doesn't appear to be an authentication issue.
    • Content type in header is correctly set to application/json.
  • Updating property values even though response is OK.

 

Any guidance would be appreciated.

    Hello rsloma,

     

    I suppose that it is due to this settings to enable :

    I think that's in Trial instance, this setting is switch off and it cannot be switch on for some security reasons.

     

    Best regards,

    Hello rsloma,

     

    When running the Python program, do you have a look to log files in Thingworx  ?

     

    If a problem occured in Thingworx, it will be quick and accurate to identify it with a verbose in log files, specialy in SecurityLog.log and in ApplicationLog.log files.

     

    Best regards,

    Samuel
