Description

Although Spotfire Web Player 7.5 or later supports TLS 1.2, disabling TLS 1.0 on a portal that hosts the Web Player mashup may make it fail to load analysis files. The web page may throw the following error: 

     Could not create SSL/TLS secure channel

.NET application communicates on TLS 1.0 by default unless otherwise forced to use a strong encryption.
