Unable to download files

[leveled]

Actual behaviour

I recently migrated my owncloud installation to nextcloud (via the instructions here) and although behavior on the desktop client and web client is functional, I am unable to download files from the android client.

Steps to reproduce

I'm not sure how to reproduce this issue.

Environment data

Stock or customized system: Customized (migrated from Owncloud)
Nextcloud app version: 1.3.1
Nextcloud server version: 10.0.1

The file is not a shared file and like I mentioned before, there seems to be no problem using the webui. After looking through the thread here, where users faced a similar issue there seemed to be an issue with email fields in LDAP. However, I have not enabled LDAP on my installation.

Hi @leveled Sorry to here that. Calling the server know how @MorrisJobke @nickvergessen @LukasReschke and @rullzer any idea what the issue is?

The file is not a shared file and like I mentioned before, there seems to be no problem using the webui.

Have you encryption enabled?

[leveled]

Have you encryption enabled?

I had encryption enabled in Owncloud, when I migrated to Nextcloud I reenabled it and added the correct encryption module from the app list (it seems to be working in the web/desktop client). When I ran into the error with the Android client I tried disabling encryption and decrypting all the files, but am still running into the same error, even after reinstalling the app itself.

I tried reinstalling nextcloud from scratch and am still running into the same problem. Furthermore even when I access my nextcloud instance from a browser on the phone I still am unable to download.

The logging produced some interesting output, I am not sure what exactly is going on

[AndyScherzinger]

seems to be a server-side issue, so (sorry for the repeated mentions) @MorrisJobke @LukasReschke @rullzer @schiessle @nickvergessen

[MorrisJobke]

This is known but we haven't reproduced this properly nextcloud/server#1166

[leveled]

Just for clarification it DOES work when I try to access it from my desktop browser/client which is very bizarre.

Is this still happening with the latest official release or with the latest beta?

[mr-bolle]

Hi Tobias,

With the current beta version i don't have this issue.

Thanks and best regards

[tobiasKaminsky]

Thank you for your quick reply.
Then chances are very good that it will also work in upcoming version 1.4.2.
If not, please re-open.
