[Bug ?] doesn't seem to ever be able to perform domain validation about acme-dns-01-cloudflare HOT 2 CLOSED

It sounds like you're just running into limitations of DNS unfortunately. With DNS caches everywhere, it's extremely common that the records added for verification won't propagate in time for the plugin to be happy. ENOTFOUND implies that your local machine can't find the DNS record it's expecting - either it hasn't propagated yet, or something in your setup is caching that "not found" result.

There's very little that we can really do to "fix" this, but a few things I'd recommend to give you the best chance of success:

1. Set your local DNS (or wherever you're running this) to use a service that isn't so heavy-handed on caching. If you're using the DNS provided by your ISP, this almost certainly won't have the newly updated records very quickly. Cloudflare's 1.1.1.1 public DNS is a good one to use.

2. Make sure you have verifyPropagation set on this module - it looks like you do from the logs. You can try playing with the waitFor and retries options too - setting these higher may help. waitFor defaults to 10000 (10 seconds), and retries defaults to 30.

3. Make sure you don't have a local DNS cache service. Depending on where you're running this, some flavours of linux use systemd-resolve to cache DNS records by default, which can improve performance, but on frequent changing records like for ACME verification, it can cause problems.

Hello! Thanks for the very fast response :)

I was already using 1.1.1.1 as dns and cleared the cache... however changing the waitFor to 20000 seems to have helped, it now generates certificates.

It's now working ! Thanks :)
