Download Metadata Error

kazukasi · Yesterday, 07:26 PM

I have started getting an error when trying to download metadata. The metadata download was previously working, and I haven't changed anything.

Here is the full error message. I am using a mac OS 10.13.6

calibre, version 3.48.0

It's becoming more and more difficult to download metadata. Sites are using protection to block the plugin from accessing the site. And Even if you can access the site, if you do it too many times in too short a period, you could be either temporarily blocked or your IP could be blocked.

Downloading metadata could be a thing of the past and you'd have to do it manually instead of a plugin to do it.
