Today I learned that nginx requires a special invocation to listen to IPv6 addresses as well as IPv4. On some of my other projects, this was causing Let's Encrypt certificate renewal to fail, because Let's Encrypt prefers to connect over IPv6 when an AAAA record is present, so its challenges were always returning 404, because nginx wasn't listening on IPv6. This shouldn't be affecting impress in production, because we don't have an AAAA record right now. But I'm just making this change in all my projects, to make sure this doesn't bite me in the future! |
