Hi people.

I’ve wanted to downgrade from Big Sur to Catalina again. I have downloaded Catalina and created a bootable stick. Later I have deleted the hard disc like Apple says it on his webpage. Now when I’m starting the boot manage/start manager I’m choosing the stick „install macOS Catalina“. I have to connect to the Internet with WiFi. It’s trying to start the installation but it always fails with an error -1008F. I was looking for help online but found nothing what helps. What can I do?
