As per google chrome it is a valid certificate.
It seems the rasperry is not able to validate the certification authority.
I’ve updated with the latest (http://mirrordirector.raspbian.org/raspbian/pool/main/c/ca-certificates/ca-certificates_20240203_all.deb) and still failing.
The RootCA (USERTrust) public key is available in my raspberry pi under /etc/ssl/certs/ and it is valid.
