Hi,

 

I have attached config.json and config.lua files for reference.

I am running EMS on my laptop and its is successfully connected to the thingworx server.Below are the logs:

Now i am trying to run the lua process manager in raspberry pi to bind a remote thing to the platform through local http connection and with help of EMS running in my laptop, but i think process manager is not getting connected to the EMS. Below are the logs:

Hi @SaurabhHCL.

 

From a review of the attachments you provided, we can see a couple of things that don't appear to be correct:

 

  1. The domain name needs to be verified.  We tried to hit the url over both http and https, and they both timed out:  https://pp-1812030854xq.devportal.ptc.io/Thingworx
  2. In the config.JSON.txt file you provided, you are indicating the port as 443 which assumes SSL, but the SSL tag is false.

How are you verifying connectivity?  Are you checking the active websocket connections?  Have you created a thing representation for the device you are trying to connect with?

 

We are also going to reach out to the team that manages the devportals in case there is something further that needs to done regarding the site.

 

Please let us know once you resolve the issue so we can document it here.

 

Regards.

Greetings,

 

Are you utilizing the DevPortal guide on connecting a Raspberry Pi to TWX listed here?

https://developer.thingworx.com/en/resources/guides/thingworx-raspberry-pi-quickstart

 

If so, the config.json and config.lua code is discussed on this sub-page:

https://developer.thingworx.com/en/resources/guides/thingworx-raspberry-pi-quickstart/configure-ems

 

In addition, please remember that the DevPortal hosted server is on a 3-hour timer. After that, it auto shuts down, and you must restart it via going to your hosted server page under your profile here:

https://developer.thingworx.com/en/profile/hosting

 

If the hosted server isn't running, then there's nothing to which the EMS can connect.

 

Thank you,

Jason

In addition, if your 30-day hosted trial has expired, and you're now utilizing the 120-day downloadable self-hosted trial instead, then you'll need to modify the "host" IP, Port, etc. in config.json to match your local instance of TWX instead of the hosted server.
