[desuarchive] 429 error appears repeatedly while scraping images of a thread, despite the original images being downloadable manually.

[rarelygoeshere]

Hello, I was scraping this thread on desuarchive, when I noticed the error "429 Too Many Requests" repeatedly showing up for a bunch of images I was scraping. It then stops but then started again occasionally, as seen with the image below, and the output txt file at the bottom.

I thought the images themselves were undownloadable on the thread somehow, but when I check a random post and tried pressing on its image, I found that I was able to download its image, as seen below. The highlighted text is the name of the image.

I have no special config relating to desuarchive, so Im not sure what could have caused these errors. I hope they can be resolved soon, thank you.

You should try an artificial delay, by using the "sleep-request" option, for example.

Try it with a low duration first, and gradually ramp it up until you see less of HTTP 429 errors, or none at all.

I'm trying to use "sleep-request" right now, and so far, the results are not good enough for my liking. For some reason, no matter how high I set it, I still get HTTP 429 errors really early in the scraping process. Im not sure why that's the case for this thread, despite past threads not having the same errors, but it's really aggravating to deal with. After that, I readjusted sleep request to 0, and tried using "sleep". When it was on 1, it gave me 429 errors, but so far, when it's on 2, it's able to scrape images from that thread without errors, although I feel it's obviously far slower than before (It hasn't finished scraping the thread as of writing this). While it seems like a step in the right direction in regards to solving my issue, I personally don't like how slow gallery-dl becomes using these options. Is there any other ways I can employ to prevent error 429 from occurring while retaining as much scraping speed as possible? Thank you for your time.

Edit: The thread has been successfully scraped without any 429 errors. Below is the settings I've written in order to do this.

After some scraping attempts, I've decided that the speed differences is in fact negligible and Im fine with it in the end, so you don't have to suggest me an alternative solution anymore. Thanks again for your assistance!
