Read MetaData online, no matches found

[bthuree]

Hi
Love Calibre, but every now and then when I am updating my metadata with various online sources, it fails with no matches found.

For instance, the below extract is for one of Chris Hectl latest books which I bought, and added to my Calibre library (downloaded from Amazon library to my laptop, and uploaded it to calibre after that). Then decided to update the metadata, but failed.

If I do a simple google search for amazon+B08R3123LK I find the book.

Any suggestions on what I should do to fix this is very much appreciated.

Cheers

Slow down your metadata searches.

How did I miss that one
Ok, so what does this mean?
I did it manually, one book at a time, so roughly one book per 30-60 seconds perhaps? Still to fast?

I've seen the same error during manual metadata download. I suspect it's not just me but a combined effort causing short term overloads.

Ok. Thanks much appreciated for your insight.
I'll just continue to do fetch online and if it do not work do manual look up in browser and copy paste
