Secure Socket Layer for HTTPS

Connections using insecure transport are prohibited while --require_secure_transport=ON means the server refuses anything unencrypted, and this connection is. Turn TLS on in the client: it's usually one option.
Authentication requires secure connection comes from how MySQL's default sign-in works: the first time it checks a password, it needs an encrypted connection to do it safely. Connecting over TCP with TLS turned off gets you this error, and the same command worked a minute later, which threw me at first.
error 79 at 1 depth lookup: invalid CA certificate means the certificate you're checking is fine, and the problem is one level up: the CA that signed it isn't marked as a CA. Mine had lost its CA:TRUE because I'd run openssl with no configuration file.
A Python script on my Mac couldn't open an HTTPS address: ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate. curl opened the same address without a problem. Python from python.org brings its own OpenSSL, which doesn't use the Mac's certificates, and the fix is a script that comes with it: Install Certificates.
Your dashboard currently answers on 127.0.0.1 and nowhere else, which is safe but unusable. This part gives it a real domain name and a free, automatically renewed HTTPS certificate using Caddy — six lines of configuration, no certbot, no cron job, and no renewal to forget.
Your WordPress site works, but only on your own network. This part puts it on the real internet with your own domain name and free HTTPS — using a Cloudflare Tunnel, so you never open a single port or touch your router. Then we add a Redis cache, set up backups, and finish with a clean removal.
