Ionic DevApp Timout on Windows

Hi,

I get a timout the Ionic Devapp, when I try to open an app.
The error is net::ERR_CONNECTION_TIMEOUT…
I already disable my windows firewall, but the rror persists.

In the Chrome Dev tools, the follownf ports are fwd. localhost:8010 => 192.168.2.100:8100

What could be the issue?
Is there a more comfortable solutiuon for Remote Debugging with a “real” device?

Many Thanks
Lars
