Unable to access the terminal of the work node on the UI page

[lizhaoyangre]

My OKD cluster version is 4.14. After installation, I found that I couldn't access the worker node's terminal page on the UI page. What should I do?
I found that this problem is caused by the inability to pull the debug image. My cluster is on a restricted network. How can I modify this image source?

Did you set up this cluster as a disconnected installation? If so, there should be an ImageContentSourcePolicy on your cluster that maps the original image location to your mirrored registry. This should allow oc debug node to start normally.

You can also customize the image using the --image option. For more information, please refer to How to use a different image with toolbox and oc debug node in OCP 4.
