When I open Arduino "Board Manager", I got error message

Error downloading https://dl.espressif.com/dl/package_esp32_index.json

Is the package server down?

Thanks a lot!

Does the problem still occur for you?

Can you open the link https://dl.espressif.com/dl/package_esp32_index.json in your browser?

Hello Pert,

Thanks a lot for your reply!

I just test it again now, and the problem still occurs for me. Please see the error message of "Arduino Debug" below. Arduino IDE can access package_esp8266com_index.json over IDE. (http://arduino.esp8266.com/stable/package_esp8266com_index.json)

Yes, I can open the link https://dl.espressif.com/dl/package_esp32_index.json in my browser and I can download "esp32-1.0.3.zip" manually with my browser.

I rolled back to old version "arduino-1.8.11-windows" and it works on Arduino IDE Board Manager. I can install ESP32 library.

Thanks!
