The simplest way to Troubleshoot.
I just installed PushFYI, I can't connect to it?
By default, PushFYI WebSocket Gateway listens on Port 80 and Port 443. It is possible that some or the other application on your machine is already bound to these ports. In this case you will fail to connect to PushFYI.
The solution to this is either stop applications using these ports and restart PushFYI WebSocket Gateway. Or, alternately, you can use PushFYI HTTP alternate port.
I cannot connect to PushFYI securely?
This could happen if you are using self-signed certificates. To get past this just open the pushfyi secure URL in your browser and add a security exception.
