I'm currently going through the codelab Enable local fulfillment for smart home Actions. I managed to get (mostly) everything working.
But when I try to debug the typescript app Chrome using the Chrome Dev Tools (chrome://inspect/) I do sometimes see my Google Nest Mini to which the "local execution app" is deployed. But most of the times I do not. All my devices (Dev notebook and Google Nest Mini) are in the same IP subnet.
Any hints or ideas how to troubleshoot that?
