Not a problem on your end.
Looks like Broadcom hasn't updated or maintained the location of the videos that they formerly posted on YouTube.
As a side note a the product documentation formerly found on docs.vmware.com is in the process of being moved to a new web site (techdocs.broadcom.com). Broadcom is saying that they're going to shut down docs.vmware.com at the end of January 2025, so it's "update your bookmarks" time.
I've reported this to Broadcom as a documentation issue.
