What am I missing?


Ah, the "depth=3" is the clue.  This is not talking about your leaf
cert being out of date.

https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/
looks relevant.  Your system (the one you ran "openssl s_client" on)
does not have an up-to-date CA cert for LetsEncrpyt.  That implies you've
not updated it for a while, and it will be full of known exploit holes
unpatched too.  One hopes it is not exposed to the outside...
