uacme -v -h uacme-hook.cmd issuewww.pmoylan.org  pmoylan.org ...

This looks fine to me.

Here's the result of that "issue" operation:
[D:\APPS\UACME]uacme -v -h uacme-hook.cmd issue pmoylan.org
www.pmoylan.org  mail.pmoylan.org
uacme: version 1.2.4 starting on Tue, 10 Dec 2024 10:06:27

certificate, it should not exist.
