VDP 6.1 unable to ssh using root password

Hello,

I am trying to upgrade my VDP 6.1 appliance to 6.1.1. The iso is not being detected when mounted so I was going to run the hotfix. However, I cannot upload the hotfix files to my appliance via ssh. I am able to log in to the vdp-configure web portal and the vmware console using the root account. When I try to log in using putty or winscp it is saying access denied.

Also, all the potential solutions I'm finding via google appear to be broken. I get this error when trying to access the vmware kb articles:  1$deletedMessageForViewDocumentPage

Any advice would be appreciated. Thanks in advance.
