Hello,
I'm running Node-RED on a Windows 10 device and set up a flow to control an ADAM relay module from Advantech. I'm using an HTTP Request node to connect to the ADAM module, but I'm not getting back a response. I've got the same flow set up on a device that runs on Linux, and this successfully connects and receives a response back. Both devices are on the same network. Basically everything is the same except for the operating system that runs NodeRed. I have attached my flow so you can get an idea of what I've set up. When I do a wire-shark capture between my Windows device and the Adam module, it tells me that the connection is "Forbidden". However, I can access the ADAM module by typing it's IP address into a web browser.
