When connecting to the BI Office API and TLS 1.0 or 1.1 has been disabled.

When connecting to the BI Office external API and TLS 1.0 is disabled (on the server that BI Office is installed on) it is necessary to add the following line to your code:

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Ssl3 | System.Net.SecurityProtocolType.Tls12 | ecurityProtocolType.Tls11 | SecurityProtocolType.Tls;

This only applies to BI Office 6.50 and above as before this BI Office required TLS 1.0 to be enabled.
