Hi,
I’m trying to add the ESP8266 Board to the Arduino IDE and I’m getting the following error.
I’ve installed the latest IDE software.
Any ideas?

Hi,
I tried but it didn’t solve.
The problem solved by running this command from command windows: setx _JAVA_OPTIONS -Djava.net.preferIPv4Stack=true

Thank for your support.

Hi Nadi,
I’ve never seen that error before and this is not very common. I’ve found this thread: https://github.com/arduino/Arduino/issues/4623
They recommend deleting the file package_index.json that is stored in ~/dist/package_index.json and restarting the IDE?
Then try to install the ESP8266 board in the Arduino IDE. Can you make sure that you copy the exact board URL?

I hope this helps!
Thank you for your patience,
Rui
