Failure when using two part TLDs (namecheap)

[snk-nick]

Authentication fails to namecheap when trying to use any .net.au or .com.au TLD. Using .com or .net domains under same account with same code work no issues.

Hook command "/etc/letsencrypt/scripts/lexicon-namecheap.sh create" returned error code 255 Error output from lexicon-namecheap.sh: Traceback (most recent call last): File "/usr/local/bin/lexicon", line 10, in <module> sys.exit(main()) File "/usr/local/lib/python3.5/dist-packages/lexicon/cli.py", line 117, in main results = client.execute() File "/usr/local/lib/python3.5/dist-packages/lexicon/client.py", line 71, in execute return self.provider.create_record(record_type, name, content) File "/usr/local/lib/python3.5/dist-packages/lexicon/providers/base.py", line 80, in create_record return self._create_record(rtype, name, content) File "/usr/local/lib/python3.5/dist-packages/lexicon/providers/namecheap.py", line 201, in _create_record self.client.domains_dns_addHost(self.domain, record) File "/usr/local/lib/python3.5/dist-packages/namecheap.py", line 373, in domains_dns_addHost host_records_remote = self.domains_dns_getHosts(domain) File "/usr/local/lib/python3.5/dist-packages/namecheap.py", line 346, in domains_dns_getHosts sld, tld = domain.split(".")

This is typically why we use in Lexicon tldextract to smartly extract out the TLD part from a domain, that is indeed .net.au, and not .au as naive .split('.'.) gives here.

Sadly this issue arises from upstream project PyNamecheap that is used by Lexicon in the namecheap provider. So we cannot directly correct the issue because the latest published version of PyNamecheap contains the faulty logic.

I would advise you to open the issue on upstream project, https://github.com/Bemmu/PyNamecheap, to ask a fix and a new version. Then I will be glad to upgrade Lexicon dependency and fix the issue on our side.

Thanks, I've opened that here: Bemmu/PyNamecheap#25

Closing this, as its related to an issue in an upstream library.

This should be re-opened now that pynamecheap isn't use dany more and the issue still exists ?

I have got this working, I think by modifying /usr/local/lib/python3.9/site-packages/lexicon/providers/namecheap.py ( https://github.com/AnalogJ/lexicon/blob/master/lexicon/providers/namecheap.py)

I added:

import tldextract

and then replacing all the occurrences of:

    sld, tld = domain.split(".")

with:

    extracted = tldextract.extract(domain)
    sld = extracted.domain
    tld = extracted.suffix
