Wildcard cert for Dynu - pip error?

[neil-west-oz]

Hi there

I'm a new-ish NPM user with somewhat modest networking skills & I am astonished at how it democratises the reverse proxy. (Huzzah and thanks, Jamie Curnow!!!)

I am trying to set up a wildcard LetsEncrypt cert for my domain, for which I use Dynu as a DNS provider, with the following parameters:

• Domain: *.mydomain.com (obviously not this one)
• Email: same as always
• Use a DNS challenge: yes
• DNS Provider: Dynu
• Credentials File Content: dns_dynu_auth_token = valid_API_token_from_Dynu

Every time I try this, I get the attached error output. Unfortunately my Linux is about as strong as my networking, so I don't have a clue what it means.

In case it matters, NPM is running via Portainer under Openmediavault 5.6 on an RPi4.

If anyone can give me a steer on fixing this, I'd be beyond grateful!

Thanks a million

Neil
