SSL Let's encrypt certificate out of date? How to refresh

Configuration
1

I’m using the Duck DNS addon on my HASS.io. It seems the certificate is out of date. How can i refresh it?

If it set up properly it should auto renew https://www.home-assistant.io/addons/duckdns/

yeah, i was thinking the same… checked my config once more. Guess what… i had ‘accept terms’ on false .

Is that a joke or what. Thanks for helping!!
