[Sun Aug 22 16:40:49 EDT 2021] Can not find dns api hook for: dns_vercel
[Sun Aug 22 16:40:49 EDT 2021] You need to add the txt record manually.
[Sun Aug 22 16:40:49 EDT 2021] Add the following TXT record:
[Sun Aug 22 16:40:49 EDT 2021] Domain: '_acme-challenge.[DOMAIN]'
[Sun Aug 22 16:40:49 EDT 2021] TXT value: '[TXT_VALUE]'
[Sun Aug 22 16:40:49 EDT 2021] Please be aware that you prepend _acme-challenge. before your domain
[Sun Aug 22 16:40:49 EDT 2021] so the resulting subdomain will be: _acme-challenge.[DOMAIN]
[Sun Aug 22 16:40:49 EDT 2021] Please add the TXT records to the domains, and re-run with --renew.
[Sun Aug 22 16:40:49 EDT 2021] Please add '--debug' or '--log' to check more details.

Here's a link to the Vercel API — if it's trivial, I might just be able to make a fix for this!
