Hi @senndoh,
Looks like that hasn't been updated to reference techdocs.broadcom.com pages from docs.vmware.com after the move - I will try and see who owns this when back at work next week and see what the story is.
This *should* be the relevant page, you may also be able to confirm that using the URL listed in the screenshot in archive.org - please validate your used passwords versus the required criteria https://techdocs.broadcom.com/us/en/vmware-cis/vsphere/vsphere/7-0/vsphere-security-7-0/securing-esxi-hosts/general-security-recommendations/esxi-passwords-and-lockout.html
