Problem downloading json file for Boards Manager in Arduino IDE

[Steve_Elves]

I had to reinstall all my software on my PC due to a re-installation of Windows. Trying to get the Arduino IDE up and running again so I can go back to work on my devices, and I find I can't install the Z-Uno2 board file in IDE version 2.3.2 or 1.8.19. Added the URL to the Additional Boards Manager URLs file (https://z-uno.z-wave.me/files/z-uno2/pa ... index.json) as before, but every time I try to install the boards it throws the following error on 2.3.2:
"Failed to install platform: 'Z-Uno2:zw_cm4f:3.0.10'.
Error: 2 UNKNOWN: read tcp 10.0.0.162:54152->185.25.224.210:443: wsarecv: An existing connection was forcibly closed by the remote host."
On IDE 1.8.19 it either throws a timeout error or a CRC match error.

Can anyone give me a hint as to how I could proceed to reinstall these boards?

Hello.
Maybe you have problems with the Internet?

Try downloading manually http://z-uno.z-wave.me/files/z-uno2/tc/ ... -win32.zip, http://z-uno.z-wave.me/files/z-uno2/tc/ ... -win32.zip, http://z-uno.z-wave.me/files/z-uno2/cor ... _00_10.zip and http://z-uno.z-wave.me/files/z-uno2/tc/ ... -win32.zip

And place it here: "%AppData%\Local\Arduino15\staging\packages\"
