This seems to be an issue on the corp network. Not sure if that means VPN or other. It looks like it is size related, this SPB is expected to be larger due to required fixes. on the database client. I am going to report the issue in general, to see if we can optimize it for next time. For now, you should work with your network admins or since you can download off corp, copy it to a drive to transfer over. You may also download the patches individually.

Note that wget was recently disabled on Oracle downloads, pages/docs might not have been updated yet.

No that is not possible as it circumvents patch entitlement. Your sr is with the patches and update team which would be correct. If everyone in your organization and only your organization is having an issue, I would next look to involve your corp network and IT people to review the matter on your end.
Can also try the alternate wget method on the download page.
