The Spotfire Server and Node Manager trust certificates are valid for 12 months. Unlike Node Manager Certificate there is no work around to manually renew Spotfire Server trust certificate at a desired time. The server checks the expiration during startup and creates a new certificate if the current one will expire within 3 months. If server has not been restarted within past 3 months and the certificate expired communication problems could be encountered.

To check expiration dates for the certificates run the command "config list-certificates -v":
1. Open a command prompt and cd into the "bin" folder of the Spotfire server. "<server install dir>\tomcat\bin"(default C:\tibco\tss\x.x.x\tomcat\bin).
2. In the command prompt run this command without the quotes "config list-certificates -v".

Sample output:

​C:\tibco\tss\7.11.1\tomcat\bin>config list-certificates -v
