16:32:52 - INFO - Guard::Shotgun has just been fired

It executes rackup just fine ( i can see my application running). But it won't do anything on any file changes.

How do I troubleshoot this?

Hi @jonyeezs,

Sorry I don't fell like I can help you. Did you figure out? It's working fine on my environment, maybe something's related to Win10? Do other Guard plugins work?

Best,
