2. Try to play local files
3. Receive error "Playback Failed: Playback Error"

Expected behaviour

• Tell us what should happen
  File should download and be playable.

Actual behaviour

• Tell us what happens
  File seems to download too fast for the file size and does not play. Streaming the file works on the iOS app. Using the app on Android, the download is successful and local playback works.

Is this a new install?

There were some reports of issues like this after updating the server, and resetting the iOS app fixed the issues.

[slowspike]

Yes, both server and apps are new installs.

I tried restarting the iphone and uninstalling/reinstalling app, but downloads still aren't working on ios. With the android app, I get a confirmation box asking if I want to download and I can also see the download in the server logs.

What is the file format? It can also be helpful to use the web UI to get the full probe data

[slowspike]

I've tried both .m4b and .mp3 on ios. I just tested downloading using the web UI and that works as well.

Are you using a reverse proxy or downloading from local ip?

[slowspike]

I have been using a reverse proxy (nginx proxy manager) and have websockets support on. I just tried using a local ip in the app instead and the download works as intended. Any suggestions for settings to tweak?

For the website that you are using reverse proxying, are you also running it through Cloudflare as well? I ask because a lot of people do and Cloudflare only allows up to 100MB uploads on the free plan, which means you won't be able to upload to your server or download to the app if the file size is over 100MB.

[slowspike]

I do use Cloudflare, but I am able to download the same files using the android app.

That is strange. For me, it's impossible to download any audiobooks on my 4 Android devices if I connect via my website that routes through the Cloudflare proxy due to the 100MB limit, which is understandable. I have to always use a direct connection (or I could untoggle my Cloudflare proxy).

Maybe your Android device is bypassing it somehow, because a 100MB limit is a 100MB limit.

[slowspike]

I just tried downloading through the web UI using the reverse proxy and it works as well.

My understanding is the 100MB limit is per request and chunking uploads is a way to share larger files. For example, I'm able to upload and share files much larger than 100MB with Nextcloud using a reverse proxy, but I did have to change some settings in Nextcloud, like client_max_body_size.

Are you able to download through the web UI when using the reverse proxy?

Disregard my comments... Yes, downloading via the web UI works, and also tested 3 of my android devices and the app works now. Was not working a couple months ago and I didn't try it again after updates. I just assumed it was Cloudflare.

[slowspike]

I'm hoping that downloads in iOS (in my particular case) will be ironed out in later versions of the app.

Seeing same issue with server 2.3.4 and iOS 0.9.66-beta, new install on the iPhone.

I'm not able to reproduce this using nginx proxy manager and cloudflare
