curl -v -HHost:passthrough.example.com --resolve "passthrough.example.com:6443:${GATEWAY_HOST}" \
--cacert example.com.crt https://passthrough.example.com:6443/get

More details here: https://curl.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
