What is the TLS version used by Spotfire for communication when using HTTPS?
While using HTTPS, Spotfire uses TLS(Transport Layer Security) protocol for communication. Spotfire has TLS v1.2, TLS v1.1 and TLS v1 enabled by default (can be located under \tomcat\conf\server.xml file), with the preference being in the same order.
The TLS protocol version chosen by Spotfire will depend on which version is enabled in the environment. If the environment has TLSv 1.2 enabled, Spotfire will use that as per the order of preference. Otherwise, it will move on to check TLS v1.1 and then TLS v1 as the last option.
