Connection to ThingWorx failed error = could not initialize a secure socket connection.

Hi experts,

I'm trying the ThingWorx Manufacturing Apps according to the guide here: https://developer.thingworx.com/en/resources/guides/configure-manufacturing-apps/configure-factory-simulator-data.

One of the steps is to open the DemoFactorySimulator.opf in Kepware, after this step I should see "ThingWorx Native Interface , Connected to Thingworx" in the Kepware's log console, however I see "ThingWorx Native Interface Connection to ThingWorx failed. | error = could not initialize a secure ".

My environment: OS:

• Windows server 2012 R2
• Installation file: ThingWorx-Manufacturing-Apps-8.3.0-05.exe
• Both of Thingworx and ThingWorx-Manufacturing-Apps are in the same machine, IP: 192.168.152.132, port: 9080

What I have verified:

• http://192.168.152.132:9080/Thingworx/Composer is accessible http://192.168.152.132:9080/Thingworx/FormLogin/Welcome is accessible
• telnet 192.168.152.132 9080 has no error
• Property Editor for ThingWorx in Kepware: see the attached picture.
• The application Key is copied from PTC.MfgSegment.Kepware_Simulator-GWKey

Is there anyting else I missed for connecting to Thingworx ? could you advise ? Thank you Regards, Sean
