Hello! I am facing to a really big problem that tried me 
. After creating my app it 's automatically log out and blocked when I am handling it. After checking the log within android studio I encounter this error: - Line 5381 - Msg: WebSocket connection to ‘ws://192.168.1.69:8100/ng-cli-ws’ failed: Error in connection establishment: net::ERR_CONNECTION_TIMED_OUT.
File: http://192.168.1.69:8100/polyfills.js - Line 6322 - Msg: [webpack-dev-server].
It 's looking like I am using websocket to communicate with the server but I am only doing HTTP request. Please HELP ME
