Downloads repeatedly stuck about bandcampdownloader

[Otiel]

But it's downloading 1 album by 1 as intended, only struggles with full discography download. Maybe add some functionality to no download them all at once (one more checkbox when downloading discography)?

If you checked "Settings → Downloads → Download one album at a time", it should work also for discographies.

Because for the huge albums like https://adrianvonziegler.bandcamp.com/album/the-complete-discography I got throttled

Thanks for the example, never found such a big album. 😄
I tried downloading it and I had no issue, so it's probably again a case of Bandcamp throttling depending on your history.

As stated in this issue, if you have those settings:

• Downloads → Retrieve file size before downloading tracks
• Advanced settings → Allowed file size difference : 5%

... then we you start downloading again the same album, it should not download again tracks that have been fully downloaded previously.

Yes, I can reach it and download manually.

Does this happen for all albums?

Does this happen for all albums?

Yes. But one strange thing happened. Today's night at 1 a.m (in my local time) app worked, and I downloaded albums without problem. But now 9 a.m and app doesn't work again.

It looks like your downloads are being restricted, most probably by Bandcamp.

Is it possible to fix?

[Otiel]

It can happen if you download lots of albums. In that case, what works usually is to wait some time before downloading again.

[kokoropop]

I don't understand how Bandcamp restricts my downloads. What principles? Why I can download manually but can't do it with app? I use this app for five years, I usually download 40-45 tracks per day, not more. Why didn't I get restrictions all this time? I need this app every day. I can't wait some time.

I'm having this issue as well. Is there simply a way to start the process over again and automatically skip items you've already downloaded? I thought the program was doing this but then I noticed after one of my download sessions froze, that the size of the destination folder actually went down from the previous attempt. This leads me to think it's actually erasing everything and starting over with each attempt??

Yes it should be skipping tracks already downloaded, if they have the same name (meaning you haven't the filename format in the meantime). Check as well that you have Allowed file size difference to 5%:

Did you notice some particular tracks that are being downloaded again when they should be skipped?

I didn't notice that explicitly. Attaching my log file. Do you think I'm experiencing the same problem as the above user? Anyworkaround?

[Otiel]

1. Yes, I think Bandcamp is throttling you in some way, which causes some downloads to fail.
2. But, tracks already downloaded shouldn't be erased. It seems there is a bug here, I should look into it.

I realized maybe it was because I unchecked the option to check size before downloads?? Still, if there's a workaround for being throttled please let me know.

[Otiel]

• I realized maybe it was because I unchecked the option to check size before downloads

  Oh yes, my bad, I missed that! If file size isn't known before download, the check can't be done. So make sure this is checked:

  

  When track downloads are skipped, you should see the following log:
  Track already exists within allowed file size range

• if there's a workaround for being throttled please let me know.

  Unfortunately, none that I know of. ☹️

Any idea what it is that Bandcamp is looking for as an indication to begin throttling? Is it number of downloads within a certain period of time? If so, perhaps you can implement some kind of "dwell time" for which the program stops downloading?

[Otiel]

Nothing certain. From what I've personally seen, it's the amount of downloads in a certain time. But people's experiences vary. Unless we could have a look at Bandcamp, we can't be sure.

If so, perhaps you can implement some kind of "dwell time" for which the program stops downloading?

There's already a cool down mechanism implemented where the program waits before retrying a failed download. But without really knowing how Bandcamp throttles, we can't implement something perfect unfortunately.

I have the same issue. But it's downloading 1 album by 1 as intended, only struggles with full discography download. Maybe add some functionality to no download them all at once (one more checkbox when downloading discography)? Or monitor download speed and download progress and repeat from there?
Or even tracks one by one... Because for the huge albums like https://adrianvonziegler.bandcamp.com/album/the-complete-discography I got throttled
