Description of bug

Fails to download a post.

Additional comments

There are currently over 300 favorite artists. If I take the interval between runs, the error will take longer to appear, so perhaps access is restricted from the kemono side. In any case, the same error occurs and the download never completes.

Can you have the api call returned valued saved next time you encounter this? (like access the api link from browser and save the content, or download the api link in download tool) I will look into this as well, with the information it should be easier

Yeah that's probably 429

"Fixed" I can't fix the server giving you 429 of course, hence the quote.
