I can reproduce this error on a fresh installation with the Nextcloud VM scripts.

Nextcloud version 15.0.7
Client 2.5.2 (Windows, downloaded from nextcloud.com)

This is the configuration in question:

# Enable HTTP/2 server wide

cat << HTTP2_ENABLE > "$HTTP2_CONF"
<IfModule http2_module>

I cannot also sync files for this bug. Please fix it. Owncloud fixed it from their latest client https://techtun.es/drFf5W and nextcloud is overlooking it.

bityoda · 2019-06-01T07:47:10Z

Same for me it's annoying. I just updated the server to the latest version. Problem persists. Is there some plan to fix this, or can i help by providing some logs?

On the nginx server side there is a warning probably related to the problem:
2019/06/15 17:07:02 [warn] 7#7: *57 a client request body is buffered to a temporary file /var/cache/nginx/client_temp/0000000004

There is no space or right problem on the server side file system.

The file to upload has in example a size of 6M. Increasing the client_body_buffer_size to 10M in Nginx has no effect. Furthermore it seems that the first client upload after starting the nextcloud client works and the next files are failing.

It would be better to link the specific github issue and pull request. I only found this one:
owncloud/client#6353
but it is already backported to Nextcloud:
e82869d

There were other issues with configuration problems. This command turned out to be helpful if the server is responding correctly:

curl --head --http2 https://<my_server/

It should give a HTTP/2 200 status and shouldn't throw an error.

enoch85 · 2019-06-16T14:50:44Z

It should give a HTTP/2 200 status and shouldn't throw an error.

In my case both my domains that are having issues throws HTTP/2 200, an they are still having issues with the client. Using the latest and the greatest of course.

ghost · 2019-06-17T18:58:24Z

I do encounter the same problem with client 2.5.3 RC2 on Windows 10 Pro.
As far I could find, it mainly happens with jpg and png files >1 MB

ghost · 2019-06-17T19:33:43Z

@camilasan Could this be related to / same issue as owncloud/client#7020 ?

possible Patch? owncloud/client@a58e439

enoch85 · 2019-06-25T17:22:59Z

I think this can be closed casue I think I found the cause.

Everyone that have the app files_antivirus enabled, raise your hand. 🖐️

I noticed that clamav was really heavy on my CPU when I uploaded files in the client and I also had plenty of issues with HTTP/2 protocol error, so I thought, "wonder what happens if I disable the files_antivirus app?"

Well, no more issues, and the syncing got much faster.

ghost · 2019-06-25T18:11:45Z

You might have a point there: I also have files_antivirus active, allthough my machine has more then anough cpu- and ram-power. It really shouldn't be a problem.

Question remains also, if the desktopclient or the files_antivirus app have a problem in combination which each other.

enoch85 · 2019-06-25T18:33:04Z

allthough my machine has more then enough cpu- and ram-power. It really shouldn't be a problem.

I ran this test on a pretty decent Xeon CPU with 12 cores added to the system, so I think that doesn't matter, rather the files_antivirus app that have some flawed code. My best guess anyway.

enoch85 · 2019-06-25T18:34:15Z

@Lars1963

Pretty funny that your avatar raises the hand btw. :D

Everyone that have the app files_antivirus enabled, raise your hand.

ghost · 2019-06-25T19:01:23Z

I raised a issue on https://github.com/nextcloud/files_antivirus. May be someone over there has a idea.

enoch85 · 2019-06-25T19:11:50Z

I'm closing this as it's most probably are related to the files_antivirus app or clamav.

Please reopen if you experience issues not related to the above.

xianx · 2019-06-26T18:15:55Z

This is not antivirus issue. Nexcloud Client throw error when HTTPS/2 is enabled on server. Where antivirus came to this issue? I dont understand. Its related to HTTPS/2 support on Nextcloud Desktop Client.

enoch85 · 2019-06-26T18:28:10Z

@xianx so you are not running files_antivirus?

xianx · 2019-06-26T18:31:58Z

@enoch85 nope.

xianx · 2019-06-26T18:40:29Z

On owncloud https://techtun.es/GeykDW they removed it https://techtun.es/OwBBvw

solracsf · 2019-09-10T17:24:32Z

Subsidiary question, any of you are using nGinx as HTTP server?
In my case, im' using nGinx and not having that problem.

ghost · 2019-09-10T17:34:23Z

Yes, I'm using NGINX and having this problem. Only solution for now is disabling http2-support for NGINX. This problem is also otherwise mentioned in combination with NGINX. see #16138

enoch85 · 2019-09-10T18:06:38Z

@acs-ferreira I use Nginx as Reverse Proxy, and HTTP/2 is enabled on both sides.

solracsf · 2019-09-10T18:17:13Z

OK, so this is not Webserver related. I'm also using files_antivirus app (ClamAV daemon not on the same server) and i can't reproduce...

felinira · 2019-10-17T08:06:07Z

I have this error too, no files_antivirus app and protocol error. Is there anything I can check to find out more? Server logs don't say anything...

kibrovic · 2019-10-18T15:13:35Z

Having the same issue on multiple devices:

OS: Debian 10 and Windows 10

Nextcloud version 2.5.1git
Using Qt 5.11.3, built against Qt 5.11.3
Using 'OpenSSL 1.1.1d 10 Sep 2019'

Windows is using 2.6.0

Server: nginx

For now, I'm downgrading to 2.3.3 which doesn't cause this problem.

Log on gist

File names replaced with FILE1,2,3. Problematic file is FILE1. I didn't include rest of the files throwing error (log show same thing).

It seems that problem is Qt http2 stack. OwnCloud disabled it

MacLemon · 2019-11-21T14:28:12Z

Same problem started popping up here recently.

Server

Nextcloud 16.0.4, 16.0.5, 17.0.1
OS: FreeBSD 12.0
nginx 1.17.6
PHP 7.2.24
HTTP/2 enabled

Nextcloud Client

macOS 10.12.16 (High Sierra)
NextCloud app 2.6.0, 2.6.1

Verified Workaround

Downgrade to NextCloud Client 2.5.3release (build 20190724) without making any changes to the server setup. (Works fine with HTTP/S and Nextcloud 17.0.1)

phonon112358 · 2020-01-19T16:18:49Z

Same issue here...
I use the Windows client (Version 2.6.2stable-Win64 (build 20191224)).
On my server, I have Debian 10, nginx 1.14.2, php 7.3, nextcloud 17.0.2.

To me, it seems that only some file formats aren't synchronised (e.g. .jpg), but others work (e.g. .pdf, .doc, .odt)... can you confirm?

As workaround, I disabled http2 in my nginx configuration for now. Everything works fine now.
However, I hope that this issue will be resolved soon!!!

lucker999 · 2020-02-05T10:00:16Z

I can confirm that for some file extensions (for instance .sh) the windows client (Version 2.6.2stable-Win64 (build 20191224)) refuses to sync with server Nextcloud 18.0 on OS: FreeBSD 12.1-p2, PHP 7.3 with http2 enabled.

Also confirm that downgrading to 2.5.3daily-Win64 (build 20190725) completely eliminated the problem.

misch7 · 2020-03-02T02:45:18Z

Also confirm that downgrading to 2.5.3daily-Win64 (build 20190725) completely eliminated the problem.

With #1823 in the 2.6.4 release HTTP/2 will be disabled by default for now and may be enabled manually by supplying the environment variable: OWNCLOUD_HTTP2_ENABLED=1

Please also see: #1397
