If you are unable to connect to the KVM console, review the troubleshooting tips below to assist in resolving the issue. Should additional issues occur, please contact support. For more information on contacting support, see Getting help and support.


The KVM console is a Java applet. Java must be installed prior to accessing the console. For more information on installing Java, see Free Java Download External link icon.

If Java is installed, ensure that a connection has been established using VPN. If a connection is not established, a warning is displayed when attempting to connect to the KVM console that a VPN connection is required.

The KVM console may generate one or more pop-up boxes during the connection process. Enable pop-ups from the IBM Cloud infrastructure customer portal to ensure a connection can be made.

You may receive an error "Java applications are blocked by your security settings." For bare-metal iKVM devices, you must add an exception for the IP Address of the IPMI device. For VSI devices, be sure to allow "https://control.softlayer.com" and the IP address of the KVM. For more information, see Why are Java applications blocked by your security settings with the latest Java? External link icon.

If the above conditions have been met and you receive an error that states, "Missing required Permissions manifest in main.jar", then Java applets have not been enabled in the Java Control Panel. This setting was introduced as a security precaution from Oracle in Java SE v7. Enable applets in the Control Panel to resolve this issue.

Note: If using Mac OSX in conjunction with Google Chrome, refer to Information and System Requirements for Installing and Using Mac Java 7 on the Java website.

If you are trying to connect to a VSI through the standard Java and are getting nothing but errors, you can also try using VNC.

If you have completed all of the checks above and still are unable to connect to the KVM console, contact Support for additional assistance in troubleshooting the issue. If a connection to the console has been made but issues occur connecting to the device, ensure the credentials being used to access the device are valid. Contact the account administrator to verify credentials, if necessary.
