Answer 1

If you from Russian or other country where Amazor CloudFlare block access for your country, you should use VPN. Using VPN me helps.

Answer 2

Unless you have a local build of the CLR, the command you're using won't work. Give it a try with: nanoff --platform esp32 --serialport COM8--update
