Hello, I am following this video [https://www.youtube.com/watch?v=v\_RUamZzby8](https://www.youtube.com/watch?v=v_RUamZzby8) and I have created an app and selected my Homey just fine. But when i try to run my app (homey app run) the error I get is that “Homey Pro (###) seems to be offline”

But I am able to connect to the app via the web UI and my iPhone app so it is definately not offline. What am I missing?

This is the stack trace:

Are Homey and Computer in same IP subnet?

Spot on!

First of all I have an Ethernet Adapter that I had plugged in the wrong way. After that was sorted out I indeed found that my development PC was not on the same subnet as my Homey. After also sorting this out it works flawlessly.

Thank you so much @Dijker.G !
