Those problems were either server or proxy related. The reason that wss:// is more successful is because SSL traffic is more opaque to intermediaries and so it is more likely that it will just be passed along without interference.

As WebSockets becomes more common, those issues will begin to dissipate as the issues are fixed in proxies, firewalls, load-balancers, and web servers.
