Fixes a bug where when you try to connect to a server using an

inexistant DNS, or having a DNS resolution error, there isnt any event
generated for the application to know.

This is not a complete fix has you need to fix a timeout value for it to
happen, but still, it makes it possible to work around it.

More work is needed on this.
