Verify if your device (laptop, tablet or smartphone) is sending all internet traffic to the PROplayer Setup network. Your phone might ask you if you want to continue using the "PROplayer Setup" network when connecting for the first time. If it does make sure you choose to connect to the PROplayer Setup network.

If the above doesn't help: reload the page, remove the power cable from your PROplayer, wait 10 seconds and re-insert it. Wait up to 60 seconds for the "PROplayer Setup" network to appear and reconnect.
