Playback Sync transmits data to ChartBuilder to auto-scroll through charts and setlists over your local network. For general setup and Playback Sync information, see: HOW TO | Playback Sync.
General Connection Troubleshooting
If running a networked audio solution (Dante, Soundgrid, etc), you may need to force Playback Sync to broadcast over a specific network. You can do this be selecting the "Network" menu before enabling Playback Sync, and selecting which network to broadcast the Playback Sync info over.
Troubleshooting Specific Error Messages
Server Connection Error. Couldn't create the required context.
This error means Playback could not connect to the required port (Port 80), or Playback doesn't have a valid IPv4 address.
If troubleshooting this error for Playback Sync on a MacOS device, use the below terminal command to return a list of current apps using ports, and search for Port 80:
sudo lsof -nP -i4TCP:$PORT | grep LISTEN
After determining which application is using Port 80, quitting that application should resolve the issue. Then re-initiate Playback sync from within Playback.
