During all this the download-progress event has not fired.

    autoUpdater.on('checking-for-update', () => {
      log('updater: checking-for-update')
    })

    autoUpdater.on('update-available', async () => {
      log('updater: update-available')
    })

    autoUpdater.on('download-progress', (progressObj: IDownloadProgress) => { // Does not fire
      log('updater: download-progress')
    })

It has worked before and I can’t really say if it’s broken for all users or not but this issue has been in here for quite a while.

@Oscabrera - hi plz use this module https://www.npmjs.com/package/@imjs/electron-differential-updater the one you are referring to is not supported by us anymore…

This issue seemingly started happening when differential downloads were fixed (#4736). When the differential download failed previously, the full download would occur and ‘download-progress’ events would be emitted as expected. With differential downloads working, the events are no longer emitted.
