starting the browser without a network connection creates an Uncaught Exception

[pmario]

Operation System: ubuntu 16.10
Beaker Version: latest master 0.6.1

To reproduce:

• Disable all network connections
• Start the browser

throws:

Uncaught Exception:

Solved with mafintosh/multicast-dns#34. Pull latest deps so you have [email protected] and you should be good to go

Hi, that still throws a low level OS error message. ... What I'd like to see in the browser starts in "offline" mode and lets the user know.

• It is possible to open file:// URIs eg: index.html

  • But the message makes a user think the browser is broken. But there is just no internet connection.

• Shouldn't it be possible to access locally saved dat repos?

What error is thrown?

The exact same info as above.

app npm list shows this:

So I'm using multicast dns latest version

I can make a video if needed.

Ah ok, it's possible that the consumer of multicast-dns isn't consuming the error event, which would still cause a throw. I'll dig deeper.
