This means that the certificate chain presented does not chain up
to a locally trusted root CA, or is expired, or some other chain
verification problem. You need to determine what certificates are
presented by the remote peer, what trust anchors (root CAs) you're
using and why the chain does not verify against these trust-anchors.

That's largely irrelevant.

That's not where OpenSSL will look by default, unless:

OpenSSL will by default look in:
<OPENSSLDIR>/certs.pem - PEM file with multiple trusted certificates
<OPENSSLDIR>/certs/ - Directory with certificate files "hashed" via c_rehash
Perhaps you have symlinks in place that lead to ca-certificates.crt,
or code to populate the /certs/ directory, but otherwise you'll
need such links, or the application will need to explicity set the
appropriate CAfile or CApath.

Your CAfile/CApath do not contain a trust-anchor that verifies the
