autoupdate files

Hello guys,
could you point me where I could download all required files to enable autoupdate? Trying to download using the tool, seems like it is not possible anymore:

Connected to 5.42.181.16:6112.
Sending ARCH/CTAG info...
Requesting info...bnftp: server closed connection

There are few files on the following link: https://wm6etsf6hqrpr6wqxjz75x5z3a-ac4c … .goog/mpq/ but not all of them.

I'd like to have set up, so my clients could update WC3 to 1.21b/1.26a (from any older version) and possibly to 1.28.5, SC to 1.18.0, D2 to 1.13c/1.14d, D1 to 1.09 and WC2 to 2.02.
From what I found in this link, I can manage only WC2, D1, D2 LOD. SC and WC3 are missing files, even ones mentioned in the config file (for WC3).

Is it possible to obtain the additional files from somewhere?
