Generally that many errors on the BadSSL cases means there is an issue with the
root certificates. Since you are running OpenSSL 3.0.7 from 2 years ago (OpenSuSE
15.4 is EOL), then some of the CA certs or intermediate ones have expired. See if
you can update to a newer OpenSSL version (3.0.18 is latest 3.0.x) or at least
update the certificates. If you can't do either, get the "cacert.pem" file from
the CURL team at Then set the SSL_CERT_FILE
env var to the of that file and try again.

Google AI says: The OpenSSL error "unable to get local issuer certificate"
indicates that OpenSSL cannot find or verify the Certificate Authority (CA)
certificate that issued the certificate it is trying to validate. This typically
means there's an issue with the chain of trust.
