#68178 Hi, may I know anyone have this problem before ?

Error downloading…/package_esp8266com_index.json

And out of sudden no ESP8266 boards available to choose in the board drop-down menu.

I am using Arduino IDE 1.8.3, at the Additional Boards Manager URLs:…/package_esp8266com_index.json

At the bottom of the IDE, the warning message: file signature verification failed. File ignored.

I have uninstall and re-install back the Arduino IDE, still same problem.

Kindly advice how to fix the above problem.

Thank you.
Best regards.

#68230 You might want to get the source directly from git-master (so disable the entire URL for the boards manager). :idea:

Since the last official releasea lot of nice features have be added and bugs have been fixed.
