"Invalid url for WebSocket ws://localhost:8080/socket.io/websocket"

[arnorhs]

Hey guys, I'm having some problems with connecting to my server using
chrome. It actually works fine in Firefox (probably using long polling
or flash socket..?) but when I try to connect using chrome I get the
following error:

"Invalid url for WebSocket ws://localhost:8080/socket.io/websocket"

The message isn't really helping so I tried googling around, but
didn't have any luck.

Any idea what it means?

Thanks (btw. socket.io is awesome)

Just a guess, but have you tried using something other than localhost
in your url?... Maybe try the fully qualified domain name, or
something like 127.0.0.1?..

For some reason my last post vanished, anyway...

Try opening the socket like this if you're not already:

var socket = new io.Socket('localhost', { port : 8080 });

I was having the same issue when specifying the port as localhost:8080.

If you're calling this from your client-side Javascript as:

var socket = new io.Socket('localhost:8080');

The port needs to be specified in the options.

Change it to:

var socket = new io.Socket('localhost', { port: 8080 });

That should work.

That was exactly it! Works like a charm now. Thanks Tim.

I guess I should have RTFM before I put in that port number :)

Cheers

Thanks Tim for helping him out.

I'll be adding support for URIs as the argument very soon. options#port is not exactly common or intuitive.
