Not related to this issue but I think that the expiration of LetsEncrypt's old root certificate "DST Root CA X3" on 21 Sep 2021 may cause quite a few problems.

Not related to this issue but I think that the expiration of LetsEncrypt's old root certificate "DST Root CA X3" on 21 Sep 2021 may cause quite a few problems. Old embedded systems may not have a way to update their trust anchors (like browsers do). Obviously not LetsEncrypt's fault but worth being aware of.
