Why won't Unity download on MacOS?

Question

iOS

Hello!
I used Unity 2018.4.17f1 before. Then they told me that a new version was released (2019.3.2f1). I went to download it but ran into a problem - it did not download for me. I explain. I downloaded this Unity Hub

. I went into it, clicked the Add button as it should, selected the version of Unity and downloaded. I waited a few minutes and suddenly the download stopped and was reset. Can you please explain why?
