This "data: 0000000000000000" refers to a specific CA loaded, the
function should load certificates from the file afterward.
If the load would fail there should be a warning like "loading ca
certs from C:\ca-cert.pem failed" but it's not present.
Also if the load fails there should be another "loading ca certs from
default location failed" warning.

Sure the C:\ca-file.pem contains the CA certificate for Let's Encrypt ?
