WebSocket connection to 'ws://localhost:35729/livereload' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED


#1

Hi, I get this error when trying to “emulate” a ionic app from the Ionic Lab:

WebSocket connection to ‘ws://localhost:35729/livereload’ failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

I suppose this is an error connecting to the ionic app within the emulator for debugging purposes?

I tried a test console.error() message in the app and it didn’t show in the Ionic Lab console.

I am very new to ionic, thanks for any help!

I remove ws folder from node_modules. After that, I execute npm install --save ws and version 3.3.3 was installed. Last release is 4.0.0, but with 3.3.3 my problem was fixed.

For remove ws module just navigate to it (node_modules/ws) trought the filesystem and delete it. After that, open your Command Line Interface and type npm install --save ws@3.3.3, or just npm install ws if your packaje.json have the right configuration for ws package.
