"can't connect to server" on Mac

[scottdraves]

For a small number of users (two reports so far), Beaker starts but their web browser cannot connect to it.

I can confirm this on a MacBook 15" running OSX 10.10. It's an earlier Mac (probably 2010-ish). I'm not sure how to diagnose what is going on but I'd like to help if I can.

got this stack trace from https://github.com/chohlasa at PyData conf:

if this call to InetAddress.getLocalHost().getHostName() fails, we should use null instead of throwing an NPE. If the value is never used then it's not an error. Really, the hostname should be more like a setting, but we can get to that later.

[scottdraves]

the above will not fix the public server option since it really needs the name. those users will have to do something like:

Steve or anyone, I believe I have a fix for this, would you care to try it out?

Here's the download link: https://s3.amazonaws.com/beaker-distributions/beaker-fix-test2.dmg

I wanted to try out beaker on my Macbook Pro OSX 10.10.1 and installed version 1.1.2. Nothing happens after I launch beaker. The app starts but it doesn't open a browser window. When clicking the reconnect link in the about menu, it opens up a browser window with the following error message: "This webpage is not available" (on Chrome).

I then downloaded beaker-fix-test2.dmg from the link above, same problem. I'm not sure my problem is related to this issue but I wanted to check before opening a new bug report.

Thanks for the report. If you run the Console app, do you see any errors
from Beaker?

Ok. Just did it. The problem was the version of java my computer was running by default (1.6). I set java version to 1.8 and all is good now.
