Certbot TLS-ALPN support for --standlone configurations?

[h_smith_usa]

I am using a Raspberry Pi Zero and serving pages on a custom web server (not Apache, Nginx, or other popular servers). It is an IoT device that supports https for secure logins.

While I can use certbot with --standalone, port 80 is not available for use by certbot. While I ran a test and confirmed port 80 can work, it does not work for my configuration.

So my question is will the certbot be updated to support a TLS-ALPN plugin for --standalone use going forward on port 443?

Thanks.

It's on the to-do list. See TLS-ALPN-01 support for Certbot · Issue #6724 · certbot/certbot · GitHub.

Support was added to the acme package. Now certbot needs to know how to use it That part of the software development hasn't been written yet.
