Recent Issue Downloading Covers on Mac

I notice a few days ago that when I would try to download cover options that I was rarely getting any results at all when previously I would get between 5-10. I also don’t seem to be getting metadata results from Amazon any more. The only time I “may” get a cover result currently it’s from Open Library. Even when attempting to search for covers on books that I know a week ago would provide me results from Amazon and Apple, I’m getting nothing. I’ve also downloaded the Kindle hi-res covers plug in, and that’s not returning results either. I’ve tried uninstalling/reinstalling, restarting my computer (Mac if it’s relevant), I’ve messed with timing settings on cover searches, and server settings for Amazon. Nothing has worked. I’ve reviewed the logs and have noticed that occasionally there will be an error related to getting a CAPTCHA screen, but most of the time the logs just say “failed to download valid cover”.

Does anyone have any ideas? I did just update to the latest version recently, but I can confirm I have successfully downloaded covers from multiple sources since updating so I’m not sure that’s it. Thanks for any help provided!
