Support for Online/Virtual Systems
QuizBowl PRO is hosted in the cloud using AWS (Amazon Web Services).  The following ports must be unblocked in order for the system to function properly:

1. Port 80

2. Port 443.

3. Port 3000 (a port used by Amazon Web Services, where we host the system)

4. Port 4000 (wss://
online.quizbowlsystems.com:4000 <http://online.quizbowlsystems.com:4000>)

The first 3 are well known and usually unblocked anyway, but the 4th one - a socket URL that handles host-player interaction - is specific to QuizBowl PRO.

Please check with your organization's IT department to make sure that all 4 ports are unblocked.
