acme client with duckdns letsencrypt and alt name has stopped renewing the cert

[jata]

Hi all

This was all working but not any longer and I haven't made any changes to my config. I am using duckdns, Let's Encrypt and DNS-01 challenge

I can successfully renew the cert if I remove the alt name (so mydomain.duckdns.org renews fine).

If I add back the alt name (opnsense.mydomain.duckdns.org) then the renewal fails.

Has something changed with letsencrypt and support for alt names?

Any assistance or advice appreciated.
