There is definitely something wonky going on with the synology. My Synology has been kept up to date on DSM versions (no longer than a week after a new versions is installed my system is updated) and I got the email.
According to Synology, it should not be possible for me to get this message, and yet I did. Since I have no way to check or verify the Synology cert renewal process, I am not at all confident that on 20 Feb I won’t be left without a valid cert.
I have a real domain name with a real IP and real DNS, not the synology.me stuff.
Anyone have a clue as to what I can do on the Synology to check this before hand? Or just force renew the cert now so at least I have a couple of month leeway instead of 7 days? Their sync-letsencrypt utility is bare bones and doesn’t even document it’s own command line switches.
