Hi,

I also have the same problem.
The fix with the command line didn't help.

Could it be, that the Github boardpackage download is down?
When I open: http://arduino.esp8266.com/versions/2.3 ... index.json
and try to download manually the .zip package that is linked in the json, I get a connection timeout.
The URL inside the .json: https://github.com/esp8266/Arduino/rele ... -2.3.0.zip

Has anyone please help me?

I'm having problems as well. I created this issue on Github: https://github.com/esp8266/Arduino/issues/3009

Edit: Disregard

I HAD THE SAME PROBLEM... I GOT IT WORKING.
Just open preferences and click on the link at the bottom (arduino15).
delete all the files inside the folder Packages and all the files with the word package in it.
restart arduino IDE.
It should work.

I have the same problem and I realized Arduino IDE converts the "http" prefix to "https" in the json link while downloading. But because of the file cannot be accessed through https, download fails
