Many hotels will require a login page to be filled out by guests when they first connect to the WiFi.
This is usually time-bound and can expire after 24 or 48 hours.
If you receive this error while being connected to the hotel’s WiFi, please open a browser on your phone to check if you need to register with the hotel’s network.
If you receive the error after verifying registration, please disconnect from the hotel’s WiFi and use your mobile data, verifying you are not on Airplane mode.
