I CANNOT DOWNLOAD ANY VERSION OF UNITY FROM THE UNITY HUB

I cannot download any version of Unity, only the one that comes by default. I tried to change the destination folder of the updates, I tried running as administrator, and also downloading without any modules. I not only did it with my computer, but also with another, I had the same result: corrupt file. After skipping this message, I downloaded and opened the 2019.2.8f1 version.
I hope a quick solution, thank you very much.

You can manually download Unity 2019.3.15

If you want to change version just change version number in URL or right-side of pages.
