I've started to get this error lately with Boards manager:

Error downloading https://downloads.arduino.cc/packages/package_index.json
Any clues how I can fit it?


Could be one of many things.

Re-start your router. (based on personal experience as the routers cache was corrupted)

See if anything changed in your computers security / antivirus settings and allow the IDE through any firewalls. (common issue)

Have you recently changed the IDE in any way eg. folder re-directions etc.

Just guesses based on minimal info supplied.
It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.
