I'm sorry but I have a hard time to parse this. The 'host' you speak of here
is clearly the server in your case.

The server requires updated SSL certs? In SSL/TLS, the server cannot enforce
that the client verifies its certificate so it cannot make -k not work.

Does it mean that the server requires a client certificate? That sounds more
likely, but it doesn't really go with your talk about a CA bundle etc further
down. The CA bundle is used to verify the server cert.

libcurl is built with a default path to find the CA bundle.

That works, yes.

No, --cacert is the option for CA certs while --cert is for client certs. You
must not confuse or mix up the various types of certificates you can use with
SSL - I know it is easily done.
