Errors when attempting to start screen redirect in LOM Technical Level
  • When attempting to enable screen redirect in LOM of Check Point Security Gateway 6200, 6400, 6600, 6700, 6900, 7000, 16000, 16200, 16600HS, 26000, 28000, 28600HS, action fails with the following error:
    Connection failed!
    The error may occur due to one of the following:
    TLS 1.2 is not enabled in the Java control panel
    The connection was closed due to a network error.
    The executed Jviewer file (.jnlp) executed wasn't downloaded to the current web session.
    The web session's certificate used by the browser is incorrect.

  • Issue takes place when attempting to connect with Java 7 and Java 8 Update 73 or Java 8 Update 73.

Changes in Java security settings - earlier versions of Java attempt to perform a connection in an insecure manner, and get connection gets rejected by the LOM.

This is not a Check Point issue.

To resolve the problem, upgrade the Java 8 package on the server that you use to access LOM to Java 8 Update 191 or higher.

Also make sure that there is a rule to allow connectivity from the host to the LOM card for TCP ports specified in sk103399 - Required open TCP ports for LOM card functionality.
