Certificate of forum expired?

not a biggo, but a bit confusing having that red warning all the time.
Could someone fix it please ?

 

Mine seems fine

 

mine expired last year.
Traced the server up on one of Hetzner server, which I know uses Plesk.
Using Https check on https://mxtoolbox.com/ it also tells me it is now valid, so nothing is hijacking my browser.
Are you maybe connecte via http ? No warnings there because no certificates are used.

 

Now that the chrome login issue has been fixed, I would appreciate if the certificate could get renewed as well
