Immediate Conversion Error when Fetching News: New Yorker magazine

[Ranman5308]

I have been using Calibre to Fetch News (the New Yorker magazine, to which I subscribe) and email it to my Kindle for several years now. Lately, upon attempting to do so, I immediately get an error message, labeled in a banner at the top “Conversion Error” followed by a message to the effect, Failed: Fetch News from the New Yorker magazine.
In earlier posts, I attached the details of the error message that I get upon pressing the “Show Details” button on the error message.

Can anyone help to get me back on track?

I share books (i.e. the New Yorker magazine) by email. I tested the email and it works fine.

The “fetch” is always unsuccessful however so there is no “job” for Calibre to email to my Kindle Paperwhite, 6th generation.

Thanks in advance for any assistance anyone can provide.
