My computer cant find "https://downloads.arduino.cc/packages/package_index.json"

Hi Matt / Dan,

I just tried with 1.8.19 and it worked OK for me. I even tried uninstalling Apollo3, close IDE, reopen IDE, and reinstall - and it worked OK:

I’ll ask our Sys Admin if he’s aware of any issues. But, right now, I can’t replicate what you guys are seeing.

Best wishes,

Paul
