So apparently, fiddling around I figured out that the keys provided through mender-configure are ECC 256 bits keys. For some unknown reason, openssl doesn’t like that the header is `-----BEGIN PRIVATE KEY-----` (I suppose it thinks it should be a PKCS#8 key). Instead, simply modifying the header to `-----BEGIN EC PRIVATE KEY-----` fixed the issues for me.
