You have upgraded JasperServer to 7.9.0 and trying to run reports that load resources such as images over HTTPS and getting the SSL Handshake error:

Solution:

The Salesforce JDBC driver has an issue that downgrades the version of TLS handshake and lots of servers will reject such attempt at establishing a handshake. If you're not using Salesforce JDBC driver please try to delete {JRS WAR}/WEB-INF/lib/TIsforce-6.0.0.000724.jar  or replace it with a driver from previous versions and restart afterwards.
