You can perform a 'curl --version' and look at differences between the
configurations. They may be too different, such that you cannot get
them to behave similarly.

You can also try a different cacert.pem:

# Fetch the latest extracted from Mozilla
curl -o cacert.pem

# Use the CA store
curl --cacert cacert.pem ...

That should help narrow the problem.
