v3.25.0 truncates domain name leading to Exception with cloudflare

[charleszlu]

In v3.25.0. When using cloudflare as the provider it raises the following exception:

Executing auth hook for domain example.net, lineage example.net.
2024-01-26 08:48:32,230:WARNING:certbot.display.ops:Hook '--manual-auth-hook' for example.net ran with error output:
Error while executing the auth hook:
Traceback (most recent call last):

File "/usr/local/lib/python3.11/site-packages/lexicon/_private/providers/cloudflare.py", line 54, in authenticate
raise AuthenticationError("No domain found)
lexicon.exceptions.AuthenticationError: No domain found

This is due to resolve_zone_name is set to True in file challenge.py, which triggers lexicon's Client to call dns.resolver.zone_for_name(domain). This truncates the domain name from example.net to just net, leading to the exception above. If I manually set resolve_zone_name to False. Everything works the same as in v 3.24.x.

I have tested using:

• Global API key with auth_username and auth_token
• Unscoped API token with auth_token

Both methods give the above exception.

I am using the below config:

acme:
  staging: false
  certs_permissions:
    dirs_mode: 493
    files_mode: 420
  crontab_renew: 0 4 * * *
  email_account: [email protected]

profiles:
- name: cloudflare
  provider: cloudflare
  provider_options:
    auth_token: <unscoped API token>
  sleep_time: 600

certificates:
- name: example.net
  domains:
  - example.net
  - '*.example.net'
  profile: cloudflare
  pfx:
    export: true
    passphrase: **********
  force_renew: false

It's the same on the duckdns provider. I had to downgrade the dnsrobocert docker container to 3.24.2 otherwise the certs can't be issued/renewed for this same reason.

In my case(cloudflare, I had set up the email):
