Amazon.com Metadata Not Working

[kevinp]

I followed the instructions in this Reddit post and now metadata downloads are working fine for me. It's a rather old post, but it is still working.

That sort of works. I'm using Amazon as my reference, and ASIN:B010OS8BQW as my test case. I did find the book on Goodreads, but its Published date was way off. It said it was published in 1969 instead of 2014. Oops. So I still go back to amazon to get the correct date and fix it.

I've be trying to get the Amazon metadata plugin to work like this

Title: Spider-Man
ids: amazon:B010OS8BQW
Author: Unknown or Author: Stan Lee

calibre, version 8.5.0
ERROR: No matches found: <p>Failed to find any books that match your search. Try making the search <b>less specific</b>. For example, use only the author's last name and a single distinctive word from the title.<p>To see the full log, click "Show details".

If I paste the query 'https://www.amazon.com/s/?search-alias=aps&unfiltered=1&sort=relevanceexprank&field-keywords=B010OS8BQW' into Firefox, it returns exactly one match, which is what I expected. For some reason the search plugin is getting a 503, though.

Also, I can find the book info here -> https://www.amazon.com/s?k=B010OS8BQ...qw%2Caps%2C179 but Calibre cannot find it. It returns an HTTP Error 503 instead.

Is there a setting I can change to get past the HTTP Error 503?
