MSIR.0646 Error requesting client certificate - (info)

A request for a client certificate on a port defined with SSLCLCERT or SSLCLCERR. 'info' gives the reason for the error. The most common reason for this error is that either the client does not support client certificates, or the certificate it presented was signed by a certifying authority whose certificate is not recognized by the port. To add a certifying authority certificate to a port, use the JANUS ADDCA command.
