Not sure if that would trigger the response.

The http:// link redirects (HTTP 301) to the https:// link.

One of the old intermediate CA certificates for Let's Encrypt (used by this site) expired today, so it may have been something to do with that. (I see the current certificate for the site was renewed today, which would also have updated the expired, intermediate CA certificates.)

Chrome caches certificates. If it is still playing up, try hitting refresh.

Excuse me where di you find the expired certificate?

Chrome with the errorr message shows the following report:
