Switching to electron 6.14 is fine

Check for existing internet connection in your main process before start the updater

I experienced the same issue with Electron 7.1.1. Two error messages appear in succession with "Error: net::ERR_HTTP_RESPONSE_CODE_FAILURE". The HTTP response code failure is a 404 status when the 2 blockmap files are requested. Since I don't use the blockmaps, the requests end with 404 Not Found. It looks like this is only a problem in Electron 7.1.1 or newer.

Could we somehow handle this Error Response? Not with this Message:

Using 7.1.1, enabling differential download option on package.json made this error message disappear, but checking blockmap process is too long and I want to skip it, anyway after analyzing, it downloads the full installer

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs.
