ACME Dynu.net DNS challenge

[chudak]

I've been using pfSense ACME "Standalone HTTP server" option for awhile with no problems.

Of cause, I have to open a port for this to work.

Recently I had to configure ACME for Proxmox as DNS challenge and the fact that there is not port opening involved is appealing.

I tried adding a second option for my configuration

and strangely enough it did not work :(

Anybody using this option and can shed light to the issue ?

Thx

What is interesting - I can setup and issue a certificate for a new DDNS name, but re-issue for the existing fails ...
