You are connected to the Hotspot’s WiFi network but didn’t get the Captive Portal and can’t access the Hotspot dashboard (http://goto.kiwix.hotspot)?

Check that you have no VPN software running as by nature those prevent direct connections and the out-server of your VPN provider surely has no access to your physical Hotspot.

If you are an Apple/iCloud+ User, mind that Icloud Private Relay is a VPN and must be disabled to access the Hotpost as well.
