  Let's Encrypt old root certificate (DST Root CA X3) expired on 2021-09-31. Newer Let's Encrypt certificates already use a new one (ISRG Root X1) since a couple of months. We use such a certificate for our CDN. Please ensure that the client to use is up-to-date. We are aware that a minority of customers currently experience issues, and we will discuss further steps during next week to avoid risky certificate replacements.
