iOS app download is very very slow

iOS
1

It's very slow to download any file on iOS (any version of iPhones and iPad).
It will be downloaded eventually after 10 or 20 minutes even the file size is quite small e.g. 20kb.
This download feature on website or Android are all worked fine, but not work on any iOS device.
I have tried many versions on App Store include the official version (3.5.3) and my built version, but the problem appear on every one.
Could you teach me how to solve the problem?

Hi, @mfshiu.

Could you share some details about your environment? What version is your OC server? What is your web server, and version? Is your server behind a proxy or load balancer?

What iOS versions are you using? Did you notice if the problem started in some concrete ownCloud app version?

Do you have the same problem no matter if using Wifi or mobile data? Is it the same if you access through Internet or in the same local network?

Thanks.

This is quite strange. Could you open an issue in https://github.com/owncloud/ios with the details of your two comments here?

Thanks.

Finally, I found the problem is caused by SSL. iOS cannot accept some SSL setting (Android is fine) so the file access was blocked. Once the SSL setting is correct iOS app is worked fine.
