Switch 2 can’t verify certificate for airplane WiFi

Idk where else to turn. I need to access WiFi on an American Airlines flight to load a game using an online license. Connect to aa WiFi, and says “user registration required.” No problem, that just means we need to load the switch’s amazing internal browser. Fine. Then I get this: error code 2809-1819. The security certificate for this page could not be confirmed. “Self-signed certificates cannot be verified.”

I click “allow” and it tries to load the page, then quickly “finishes loading” with a black blank screen.

My date and time settings are correct. I’ve restarted the switch. My phone and other devices connect to the WiFi fine. Any thoughts??
