Can't login via web (Duckdns problem?)

Hi, I can’t access my homeassistant.os installation from the web anymore. The browser says that the certified is expired 21/11/2021 but I don’t know how to force update it.
Restarted homeassistant, restarted the addon, deleted privkeys and fullchain files and restared, but nothing changed. Any hints? Thanks
(duckdns addon log is OK, the cert seems updated)

Is your system time correct?

Seems OK
