cannot connect to Thingworx from Kepserverex V6 Thingworx native interface

Greetings Metin,

Here is an excerpt from the KEPServerEX v6.2 Server Help manual, in the Event Log error message section:

"'Connection to ThingWorx failed. | Platform <host:port resource>, error: <reason>.'

Possible Cause: The connection to the ThingWorx platform could not be established.

Possible Solution:

1. Verify that the host, port, resource, and application key are all valid and correct.

2. Verify that the host machine can reach the composer on the ThingWorx platform.

3. Verify that the proper certificate settings are enabled if using a self-signed certificate or no encryption."

If any of the above parameters are incorrect, a socket connection cannot be formed between KEPServerEX and ThingWorx. Extracting from the help description, here is a checklist to go through for these items:

1. a. Host: This is the URL used to connect with your ThingWorx instance. This will be tested in Step 2 below.

1. b. Port: This is configured in the server.xml configuration file for Tomcat. The default, non-encrypted port is 80.

1. c. Resource: You will need to have a Resource value entered here. Try the default "/Thingworx/WS".

1. d. Application Key: Follow Sharon's instructions to verify you have copy/pasted the Application Key directly from Composer

2. Now, on the same PC where KEPServerEX is installed, open a web browser and attempt to connect to ThingWorx Composer at this address:

<Host>:<Port>/Thingworx

3. Unless you are using SSL or self-signed certificates, the best options for the three certificate/encryption options are:

Trust self-signed certificates: No

Trust all certificates: No

Disable encryption: Yes

Please let us know how it goes after going through these settings and suggestions.

Best regards,

Steven M
