Just to be clear, you're serious right? Because yes, the Wii U has a browser, it hasn't been updated (because the Wii U is basically abandoned at this point) and it never did trust DST Root CA X3, which is the root via which trust to Let's Encrypt was bootstrapped in older browsers. Don't happen to have links for any of those tweets do you? I'd be happy to have an actual example of a user who ran into this for real (nobody can fix it, but it's good to be reminded they exist)

The problem wasn't just because of the HTTPS cert, but also because it didn't support WebSocket on port 8000.
