In some cases it is not practical or wise to keep port 80 open all the time so that Let's Encrypt can automatically renew on a Synology NAS. For example, I don’t need port 80 open to the internet for my home NAS. Since it is a well know port nefarious people are constantly scanning for port 80 on the internet. Since I don’t need it for anything I’d prefer to just keep it shut down at the router and not worry about it. Even if security wan’t a concern I just want to keep the traffic from these unnecessary scans off my network. So I manually renew the certificate every 60 to 90 days.
There were enough updates this week to keep us busy. Around 7 packages were updated (depending on how you count the Cloud Station related packages). If you run a Synology NAS then you probably run one or more of these packages.
