How do I make work with my custom daemon process?

If you are using custom proxies and daemons to serve your site content, following the recommendation to use our to set up free TLS from Let's Encrypt takes an extra step.

When you request a certificate via, a temporary file is created in the /home/public/.well-known/acme-challenge directory. Let's Encrypt checks that file by requesting it from your site using the URI /.well-known/acme-challenge/. In most cases, that "just works" because Apache handles it for you. If you have a custom process handling requests for / (i.e., all requests for the site), that won't work. The request will come to your daemon instead, which will likely say "What the 🤬 is this?" and return an error, causing your TLS setup to fail.

You should do one of two things to resolve that, depending on your server type:

Once this is set up and working, leave it in place. Your certificate will need to be renewed every 60-90 days, and this is part of that process.
