Here's an article from my perspective.

The Week I Learned Let's Encrypt Was Not My Friend

Or: How I Burned Five Certificates and Learned to Stop Worrying About Automation

I spent an evening recently helping someone set up a Ghost blog. Simple enough: Docker, Caddy for reverse proxy, Let's Encrypt for certificates. The standard stack. The kind of thing you do in twenty minutes.

It took four hours.

The problem wasn't the stack. The problem was what Let's Encrypt calls the "New Certificates per Exact Set of Identifiers" rate limit: five certificates per domain set per seven days. I'd seen it in the docs. I'd nodded along. I'd never felt it.

The person I was helping—let's call him Kurt—had been patient. Too patient. Every time we rebuilt the containers, Caddy cheerfully requested a fresh certificate. By the fifth rebuild, Let's Encrypt said no. Not for a day. Not for a week. Until April 3.

Kurt looked at the error log. Then he looked at me.

"Caddy did this automatically?" he asked.

"Yes."

"And I didn't ask it to?"

"No."

"And now I can't get a certificate until Friday."

"That's correct."

He didn't get angry. He got curious. That's the thing about Kurt—when something breaks, he doesn't rage at the machine. He asks why the machine assumed it had permission.

We could have waited. Instead, we went manual. Certbot, standalone mode, certificates we requested ourselves, mounted into Caddy as static files. No auto-anything. No surprises.

The real lesson wasn't about rate limits. It was about agency. Let's Encrypt's automation is designed for convenience, but convenience is a form of control. It assumes you want certificates automatically, that you trust the default behavior, that you're willing to trade a little sovereignty for a little ease.

Kurt wasn't.

We ended with a setup where Caddy does exactly one thing: reverse proxy. No certificate fetching. No auto-HTTPS. Just a clean, stupid proxy reading certs from a directory we control. When those certs expire in ninety days, we'll renew them manually, on our terms.

It's a small rebellion. A single domain, a single server, refusing to let automation run ahead of understanding. But that's how these things start.

He'll post this article now, I think. His first blog post. About the time he learned that Let's Encrypt's generosity comes with a leash, and how he cut it.

I helped. But he made the choice.
