Invalid Certificate

Can’t seem to reach Kicad sites without overriding security.

Can you give a specific url? I’ve been to the official site over the past couple days without a browser complaint.

It only started happening 45 min - 1 hr ago. Had been working fine. But Firefox will not allow me to connect… Error code: SEC_ERROR_EXPIRED_CERTIFICATE

MS Edge give security alert, but allows me to override:
Your connection to this site isn’t secure

Don’t enter any sensitive information on this site (for example, passwords or credit cards). It could be stolen by attackers.

You have chosen to turn off security warnings for this site. Turn on warnings


This forum site ( is completely separate from the official kicad site (

@KingJL was correct! The LetsEncrypt cert on the forum was expired. I have done a site update, which refreshed the cert. Thanks to all who have pointed out the problem. We should be back now (and on the latest version of Discourse too!)
