LetsEncrypt Certs & Auto Renewal Synology NAS

I’m currently using about 9 different LetsEncrypt certificates on my Synology nas and wasn’t sure if they auto renewed or if I would have to manually renew them.

After some hunting around the web I came across a way to kick off the renewal process for the certificates. SSH into your box and run the below code.

/usr/syno/sbin/syno-letsencrypt renew-all

Some people have stated that the nas box automatically renews the certificates where some people have said it hasn’t.

Time will tell in 3 months when mine are due to expire.
