The monitoring dashboard in ProcessingJob and TrainingJob in the SageMaker console is not visible.

Here's what I checked:

• Logs coming into CloudWatchLogs are all good
• CloudWatchMetrics dashboard shows all metrics well
• In the Experiments-Trial dashboard within SageMaker Studio, all is well displayed.
• Tested in other browsers & secret mode, the same symptoms occur
• The IAM User under test has Admin privileges

The suspected cause is a failed request in the browser console and network tab, and a 403 Forbidden error occurred when requesting the amzn.css static file to cf.

• Request URL: https://djj80sfhnqgai.cloudfront.net/948cfe73f907787e734e6bb4193359ed4c68cbc8/cloudwatch/amzn.css
• Method and Response: GET/403 Forbidden
• Error related message in response header: "X-Cache: Error from cloudfront"

Are there any missing settings or additional checks when executing a job?
