Unable to renew Let's Encrypt certificates anymore

[runekm]

Renewing Let's Encrypt certificates have started failing here with version 0.9.1 of Redbird. I also tried upgrading to Redbird version 0.10.0, but that didn't solve the problem. I also tried deleting the old certificates from the /certs folder, and then restarted Redbird. When I do that, the certificate folder is recreated with ./well-known/acme-challenge/test-[some random string]-0 inside it. But the process stops there, and none of the .pem files are created.

Any idea what is the problem?

no idea, it should be working. Did you try with the simplest setup and go from there?

My setup is quite simple. It looks like this:

var proxy = require('redbird')({
    port: 80,
    xfwd: true,
    bunyan: false,
    letsencrypt: {
        path: __dirname + "/certs",
        port: 9999
    },
    ssl: {
        http2: true,
        port: 443
    }
});

proxy.register("mydomain.com", "http://localhost:3000", {
    ssl: {
        letsencrypt: {
            email: "name@email.com",
            production: true
        }
    }
});

This has worked flawlessly for a couple of years, before I suddenly realized that the certificate wasn't renewed anymore. I spent some time trying to debug the problem. But I find it a bit hard to debug, so I didn't come far.

My temporary solution - which I might make permanent, if the problem persists - is to use a certificate created with Certbot instead. Certbot created the certificate without any problems.
