Did you ever figure this out? I have a socketIO server running on Heroku. I'm unsure what port I'm suposed to be listening to be listening to. My javascript client works when I don't specify a port number. With this library, I don't have the option of not specifying a port number.

@ShreyasSA I fixed my problem but it was something trivial. If you give me more information I can help you debug your problem.

Hey guys,
I'm facing the same issue here. When I connect to the server on a browser using the same URL it works fine but when I try to connect thru my Xcode program it throws an error! Any guess why this could be happening?

[SivaDotRender]

I think a common mistake is to not omit the "http://" part of the host url when using the connectToHost method. This is added automatically. So instead of "http://www.example.com", use "example.com".

[anuradhavasudeva]

BTW, I altered my code to send a proper URL...as follows. I think Socket IO
appends http on its own ..so sending http is redundant..so my call to
connecttohost looks like this :

[_socketConnection connectToHost:@"bubbleme.azurewebsites.net"

onPort:80 withParams:nil withNamespace:@""];

I get the error below now...

@anuradhavasudeva I suspect the port you have used is wrong.
