Nextcloud server has no domain name, only ip address with snakeoil certificate.
Pdf file was downloaded and could be read. But not initially by app.

avalx · 2020-01-20T17:35:25Z

I have the same problem, not only PDF but other files as well (odt, doc for example). And sometimes it only happens the first time I try to download/open a file, when I restart the client and try to open the same file everything works OK.

Here is my log:

I also noticed that this only happens when using the client with my local/internal NC server (signed with my own CA). Using the client with Disroot.org for example does not produce such errors.

avalx · 2020-01-20T17:49:54Z

Just to add another observation. This problem only occurs if I tap on the file I want to open. If on the other hand I tap on the 3 dot menu and choose "Download", the file is downloaded without errors and I can than open it normally.

AndyScherzinger · 2020-01-20T21:25:58Z

Cc @tobiasKaminsky and @ezaquarii for okhttp topic

kellnerp · 2020-01-20T21:39:21Z

Avalx. The behavior you mentioned has happened frequently, but the crashing and error report is new. Not just pdf, but videos.

kellnerp · 2020-01-23T02:03:06Z

Also text files cause this error until they have time to download.

tobiasKaminsky · 2020-01-23T11:17:12Z

Is this with self-signed certs?

kellnerp · 2020-01-23T11:33:44Z

I am using self signed certs. It is a private storage without domain name.
Nextcloud has always choked when trying to play or display anything forever. Only recently have these error dumps showed up.

moviuro · 2020-02-01T20:59:38Z

I have the same issue as otherwise reported on my own server https://sco.popho.be (TLS 1.3 only, Let's Encrypt certificate, nginx). Crash report below.

I have had this happen frequently since I first reported it. If I can download the file first then the error generally doesn't occur. Never had this problem with Dropbox. It streams anything streamable without complaint.

If this could stay open until the 3.10.2 client is published, it'd be better IMHO.

BTW, the crash still happens on 3.10.1 (not surprising considering all the latest commits were done on 2020-02-07 when 3.10.1 was published on 2020-02-05).

tobiasKaminsky · 2020-02-11T05:51:31Z

Can you try out our dev version (you can install it in parallel) and give us feedback:
https://github.com/nextcloud/android/blob/master/CONTRIBUTING.md#developement-release

avalx · 2020-02-11T09:06:08Z

In my case the version 3.10.1 also works OK - pdf and other files as well.

moviuro · 2020-02-11T17:28:42Z

@tobiasKaminsky the 20200211 version of the dev app seems to behave correctly!
