UCS upgrade problem

Hello there!

I have 2 UCS Servers, one master (ucs01) and the other is backup (ucs02). Both have no direct access to internet, We have a proxy server that is not under our administration.

After receive the message " The currently used UCS version is out of maintenance. Please visit the “Software update” module for more information" we tried to upgrade with no success.

In ucs01 it shows this message, at “Software update”: https://pasteboard.co/IZng6d2.png

And at ucs02 ther it shows this message: https://pasteboard.co/IZngKau.png

Need help to update both servers.
