media.kbin.social has an expired certificate

Not sure where to report this exactly but media.kbin.social has an expired Let's Encrypt certificate (expired Tue, 03 Oct 2023 14:47:25 GMT) and this is causing problems loading various images across the site -- e.g. user avatars (sometimes), images copied from various Lemmy instances, and image threads made on kbin.

It doesn't affect all images though as some are loaded from kbin.social/media instead.
