    I've just found an odd issue with Let's Encrypt...

    I have domain.co.uk setup, with Let's Encrypt SSL, and it was working fine.
    I then added beta.domain.co.uk, with Let's Encrypt SSL, and it made domain.co.uk redirect to beta.domain.co.uk, causing a redirect loop.

    Both had 'Auto-Subdomain' set to 'None'.

    Any ideas what could be causing this please? I'll try and do more testing, but I'm a bit reluctant because it's not a site I want to be offline.

    Both nonwww and www for domains and subdomain must work when letsencypt generate cert.
    Check your letsencrypt log.

    And you need to have a CNAME or A Record for every single (sub.)domain.tld in your dns zone file - at least I think it's still required. Do that means you can't have like * IN A xxx.xxx.xxx.xxx and request a LE cert for xxx.domain.tld
