NYR back issue - fail to download images

[nano5]

When using calibre recipe to fetch nybooks back issues, sometimes it fails to download article images, not all images but some of them.

Is it network issue, e.g. too many requests too often, or due to the image format in such back issue articles? such failed images can be opened in web browser and downloaded individually.

If you look at the full log it will tell you why it failed, the image is in jpg so it cant be because of image format, most likely server throttling.

Thanks likely a network traffic issue when the connection is not good/fast enough
