My server has had issues using websockets to connect to clients with high latency, so if you're faraway from where I'm hosting it (Northern California), it may not connect. Also, I haven't done load testing, so this may be a cause as well.
when the permissions say "Your data on all websites" and its connecting to your server, what exactly do you see ? Cause I know with this permission it allows for example to see a banking site if we were on it.
