Problem

Getting "Insecure Negotiation is not allowed" error message while trying to connect to a remote SecureTransport server, using SecureClient.

Resolution

This error occurs because the server you are connecting to requires SSL/TLS.

To fix this, enable the "Use SSL Cache" option on the Security tab of the site details. Also set the "If server has an unknown root certificate" option to "Accept connection" (on the same tab).
