Hi @michelandre,
I started the next attempt.
- Deleting content of:
/* etc/letsencrypt/live/
- /etc/letsencrypt/archive
- /etc/letsencrypt/renewal
- cerated /etc/letsencrypt/live/FQDN1
- chowned root:root /etc/letsencrypt/live/FQDN1
- requested new certificates only for all FQDN1-Domains (smtp., imap, www …)
- get an error
- refreshed the page within the browser: the new certificate exists
- applied as the standard certificate /etc/letsencrypt/live/FQDN1
- get an error
- refreshed the page: seems to be assigned as a standard certificate
—> forgot to create the additional /etc/letsencrypt/live/FQDN2. - added the the second FQDN2 within the request form
- get the same error as above and no new FQDN2 related certificate was created
- have assigned the certificate to the vhosts
- opened the website in the browser and checked the certificate: all FQDNS were bundled in the FQDN1 certificate like SANs
I will try in seven days again and change my procedure
- add the directory after Step 9
- perhaps no adding FQDN2 to FQDN1 but substitute FQDN1 by FQDN2 in step 10
sincerely, Marko
