using bad --relay-url= gives an unhelpful traceback

After installing wormhole (from pypi release or github’s master), when I follow the example commands I get an exception:

Unhandled Error

With latest version:

ERROR: We had a problem connecting to the relay server:
(relay URL was ws://relay.magic-wormhole.io:4000/v1)
connection was closed uncleanly (peer dropped the TCP connection without previous WebSocket closing handshake)

I can netcat, but http GET half working:

http: error: ConnectionError: ('Connection aborted.', error(104, 'Connection reset by peer')) while doing GET request to URL: http://relay.magic-wormhole.io:4000/

I’m using autobahn[twisted]>=0.14.1.

But, still good news: using localhost server it works! A configuration file to set default server would be awesome 😉

@merlinengine I was upgrading the server about 6-9 hours ago, so it’s possible you ran into the 5 minute when the server was down. If you try again now, do you see any problems?
