Can't run app on device with logging options

Hello,
I’m having issues getting serverlogs and consolelogs to work on RC3.
I’m running ionic run android -l -s -c --device and I get this warning during the process:

The port was taken on the host 192.168.0.34 - using port 8000 instead

The app then loads to a black screen and shows a popup that reads:

Application Error
The connection to the server was unsuccessful. (http://192.168.0.34:8000)

Any help is much appreciated. Thanks!
