    0x800b0109=A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.

    This error is usually due to the client certificate authentication is not configured properly. Check on the client if there is a self-signed certificate present in Trusted root Certification authorities certificate.

    You need to make sure that you install the self signed certificate to each client device so that it is trusted.
