Can't connect to server on port XXXXX

I’m having a problem when trying to access one of the projects through the .dev domain. The output that appears in the browser is as follows:

Can't connect to server on port 45355. Server crashed or timeout of 5000ms exceeded. Retry or check logs.
sh -c npm start


> pomodoro-app@0.0.0 start /home/julianorafael/Development/projects/pomodoro-app
> cross-env NODE_ENV=development node server.dev.js

Starting server...

Just in case others encounter the same issue, @jalada has found a workaround. You need to bind to 127.0.0.1. There’s usually an option for that, for example with Rails it looks like this:

hotel add 'rails s -p $PORT -b 127.0.0.1'

However, feel free to report issues with other servers.

I can confirm this problem. I’m using ruby with sinatra. Everything worked/works fine when i’m using the WEBrick server but as soon as i install the rubygem ‘thin’ i’m getting the same problem (-> after installing thin, sinatra starts the thin webserver).

Console output when running with WEBrick (working):

2016-04-06 14:35:13] INFO  WEBrick 1.3.1

Maybe it helps in the debugging process 😉

I’m using WEBrick for now.
