How we fix Supermicro java console connection failed

Recently one of our customers contacted us to resolve java console connection failed error.

Add IP to the exception list

This error occurs because the current version of Java no longer allows self-signed applications to run by default. In order to allow the application to run, the URL of the IKVM device must be added to Java’s site exception list. We provide the below steps to our customers to fix this error.

1. On the local machine open java and select configuration Java.

2. Within the Java Control Panel go to Security.

3. Select Edit Site List

4. Now add the IPMI IP address to the list.

http://ipmiip
https://ipmiip

5. The remote application will try to connect using SSL. Thus https must be added.

5. Then relaunch the remote console. Now an SSL warning message appears. Click the checkbox and click on continue.

Now will be able to access the console.

Update JAVA

One of the common reasons the error is that the JAVA application is not up-to-date. We recommend our customers to update the Java in the local machine and try to connect to the remote console.

IPMI firmware

If the IPMI firmware is not up-to-date. We can get the console connection failed error. So we update the firmware. Let’s discuss how our Support Engineers update the firmware.

1. We log in to the management interface. Then go to Maintenance and select Firmware update.

2. Now we enable update mode by clicking the Enter Update Mode.

3. Then we upload the ZIP file. Once the file is uploaded the screen will show the current and the newly added firmware.

4. After confirming the version we select start Upgrade.

5. Once the update is complete the management interface will reboot. It will return back to the login screen.

Now we login to the console and we can access the remote console.

If we still face an error even after the update we use the Factory Default option in the web interface to connect.

IKVM port

If the IKVM server port is not opened in the server. The console will fail to open.

We will be able to access the management interface since it uses port 80 and 443. We check the port from the web interface and open the port in the firewall.

After opening the port. Then we will be able to access the remote console.
