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.
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.
