I am using Arduino 1.8.10.
I added http://arduino.esp8266.com/stable/package_esp8266com_index.json to Boards Manager URLs and got a downloading error.
"Error downloading http://arduino.esp8266.com/stable/package_esp8266com_index.json"
is the error showing.
I have tried deleting sam folder, deleting .json files in hardware folder but nothing worked.
what should i do?
