For the archives:

- I pulled down latest version of nginx-quic and built it. The error seems to be resolved. First page on the site now shows http/3
- As for https://http3check.net https://http3check.net/, the reason it failed was I had the root page protected behind basic auth. Since it doesn’t send auth info, it 401’d and caused the page to throw an error. I’m going to write to them and ask them to toss up a clearer answer, whether it’s a negotiation error or a http error.

Thanks for the assist. The debug log is where I found the 401
