When for some reasons, the Let’s Encrypt certificate has not be renewed on your Synology and those bloody stupid Web browsers won’t let you connect to the DSM for “Security Reasons”, you can still count on SSH to solve the problem.

# /usr/syno/sbin/syno-letsencrypt renew-all
Where there’s shell, there’s a way.
