I'm really not sure if this will help, but figured I'd throw it out there -- I've seen similar looking errors in the past when it couldn't download the Goodreads...
See my response to https://github.com/na--/ebook-tools/issues/14 -- not sure, but it's possible that pull request mentioned in there will help.
Best start for debugging is to try running the standalone tool -- see the main repo here: https://github.com/instaloader/instaloader This one's just for the (rough) docker wrapper.
Just a guess based on pubDateTime in your screenshot vs the date/time when you posted this -- is the pubDateTime in the future? If so: https://github.com/satnaing/astro-paper/pull/234
