Apologies for the delayed response on this one. Or we should trust, at least, the authority that is endorsing the Issuing Authority, which we call Root Authority. Affected applications might return different connectivity errors, but they will all have untrusted root certificate errors in common. The reason you had to provide both intermediate CA and root CA for verification to work is that wolfSSL checks the signatures and rebuilds the entire chain of trust.

When you receive it, you use the combination of the key you know from your trusted authority to confirm that the certificate you received is valid, and that you can therefore infer you trust the person who issued the cert.

Connect and share knowledge within a single location that is structured and easy to search. CACert.org has this same issue, it has valid certificates but since browsers don't have its root certs in their list their certificates generate warnings until the users download the root CA's and add them to their browser. time based on its definition.
