Your phone skipped the WiFi sign-in

Something on this phone sent the sign-in to the internet instead of to the WiFi, so it could not finish. To fix it:

1. Turn off any VPN or ad-blocker app.
2. Set Private DNS to Automatic or Off (Android: Settings, Network, Private DNS). On iPhone, remove any DNS or VPN profile.
3. Forget this WiFi network, join it again, and sign in.

Your account and any plan you bought are safe. If it still fails, ask the venue for help.
