Renewing Let’s Encrypt in Synology DSM 6

Since I don’t want to open port 80 permanently the effort to renewing LE certificate is doubled.

So this is a note to myself, the step to renewing LE cert is the following:

  1. Install/Run Webstation
  2. Disable firewall
  3. Open port 80 on the router
  4. Go to Control Panel –> Security –> Certificate –> Renew the cert
  5. Enable firewall
  6. Close port 80 on the router
  7. Uninstall /Stop Webstation (don’t want to have useless app running)

If I remember this last time, it will only take 15 min max for me. I can manage to do this 4 times a year :D
