[Bug]: Can't download audiobooks

[Cossty]

What was the Problem?

Recently, I finished setting up audiobookshelf for the first time. I decided to download 30+ audiobooks. Some of them have multiple tracks, so the android app was downloading around 400 files. After it downloaded around 100 it was stuck and didn't continue. I had to restart the app, disconnect and reconnect to the server, just to be able to download again. Tried again to download a lot of files at once. Same result, stalled after a while.

Then I tried to find some answers here. The only thing I found was that when you start downloading a book, you should wait a little on it's page, to let the download set up. So I did that, I waited on each book 5-10s, before leaving for another one. It looked like it helped a little, because a lot more files got downloaded this time, but it stalled anyway. My internet is downloading books 5-6 m/s.

After that, I was downloading books one by one, which worked until it didn't. I have 42 local books. Audiobookshelf app uses 25.61 gb of user data. Now the download stalls before finishing one book. Connecting on local network. Battery optimization is set to unrestricted.

Steps to Reproduce the Issue

1. Have no local books

2. Que a lot of books/files for download. 400+

3. Have a 42+ local books/25.61gb of user data

4. try to download another book

What was Expected?

To be able to download books without stalling.

Phone Model

Fairphone 4

Phone OS

Android 13, stock, but stock for fairphone is /e/OS

Audiobookshelf App Version

Android App - 0.9.74

Installation Source

Google Play Store, Other (List in "Additional Notes")

Additional Notes

App downloaded with Aurora Store, but if I understand it correctly, that's just google play version. I don't have logs for when I was downloading a lot of books at once. There are a lot of ping timeouts in my logs, is this intended?

I don't know if this is the reason for downloads stalling, but they sometimes stall without there being ping timeout in logs. Like here

It stalled after file 37 and I had to restart the app and disconnect and reconnect to the server. Here I tried to download it again, but it stalled on file 20, timeout happened 5m later, so that was probably not the cause.
