Title: ACME Client With Cloudflare Invalid Domain Error
Post by: paf23 on March 20, 2026, 02:03:43 PM
Can anybody help an advanced beginner with this quarter's ACME issue?
Last time my certificates needed renewing I managed to fix the error which seemed to be related to Subject Alternate Names but this time I don't have any SAN involved but am getting the Invalid Domain error using a DNS01 challenge type
I found one suggestion to amend /usr/local/share/examples/acme.sh/dnsapi/dns_cf.sh  but that didn't help

Opnsense version is 26.1.4

Ignore - it was the SAN thing again afterall!
