- Open your 443 port in the direction to your synology server.
You have a command to renew in CLI the certificate manually:
-v is for verbose
So, you just have to create a bash file and include this command in it
For example create it in this repository :
Then create a bash file " auto-renew-letsencrypt.sh " for example :
Go to the synology admin webpage
Open "Control Panel > Task Scheduler"
Then create a user defined script
Add your script in the task settings pane.
Schedule it to renew every 3 months :)
