acme-dns-auth.py doesn't work for me

[etcware]

When I run certbot with the suggested command line I receive the following error:

Hook command "/etc/letsencrypt/acme-dns-auth.py" returned error code 1
Error output from acme-dns-auth.py:

These are the versions I have on python-requests. Do you have any suggestion?

I had a similar error when working with ACME-DNS directly.

Do you get the same error when you try testing the process: https://github.com/joohoi/acme-dns#testing-it-out

I fixed mine by updating to the latest version and making sure it successfully received a LE cert.

@etcware Still an issue for you or can this be closed?

Were you running your tests against a self-hosted version of acme-dns? Were you running against letsencrypt staging?

acme-dns server does not retrieve a Let's Encrypt certificate for localhost as this is not allowed by LE.
It retrieves a certificate for its domain.
You must use that domain to connect to the acme-dns server, otherwise you get a certifcate error (non matching domains).

I wrote my own acme-dns-client that works with certbot and acme.sh.
Please have a look here: https://github.com/maddes-b/acme-dns-client-2
Feedback welcome.
