That's complaining about the "DST Root CA X3" certificate, and that's
(partially) expected: https://letsencrypt.org/2021/10/01/cert-chaining-help.html
But the fact that you're seeing this indicates that you're either
running an horribly outdated version of openssl (as Daniel mentioned),
but even CentOS' "OpenSSL 1.0.2k-fips 26 Jan 2017" has been fixed
in this regard.
The other possibility is that your trusted CA list is outdated: that
would be package ca-certificates (same name in deb and rpm world).
I do know from my own experience that at least the "old" (2020.2.something)
Redhat package is missing the new "ISRG Root X1" certificate, you'll
need version 2021.2.something.
Regards,
Christoph
