Cause

The Java™ Runtime Environment that is used to start the Problem Insights server does not support some of the encryption ciphers that are configured for use by the Problem Insights server.

Solution

Complete the following steps:
  1. In the INSTALL_DIR/config/cli.config file, update the value of the ciphers property to list only ciphers that are supported by the Java Runtime Environment that is used to start the Problem Insights server.
  2. Save and close the INSTALL_DIR/config/cli.config file.
  3. Restart the Problem Insights server.
