Thingworx Remote Access Client: Connection to TWX on AWS failed

Hi guys,

I'm working with the Thingworx Remote Access Client and I want to connect this with TWX which is running on AWS.

When I start a connection via the RemoteAccessClientLinker-Widget the RA-Client starts and try to connect and timed out after few secondes with the error message:

Unable to connect to Thingworx; ensure platform is available at <xxx.xxx.xxx.xxx:443> and that proxy settings are correct

Last week I try the same with a PTC-Hosted Thingworx and everything works fine. On my AWS hosted Thingworx it will not connect. Strangely it works fine with the old Remote Access Widgets.
