digest_error: NONE: not usable
This can occur if you specify auth none and also tls-auth in your client profile. This occurs because tls-auth needs an auth digest, but none was specified. There’s a straightforward fix: just remove the tls-auth directive, since it can’t be enabled anyway unless you have anything other but ‘none’ in the auth directive.
