Owncloud webinterface resets when uploading file

[JBecker]

Hello everyone,
Im using Owncloud on a raspberry pi with apache2.4+mariadb+php7.
When i try to upload a file >10kb with the owncloud webinterface, the page reloads and the owncloud log says:

$this->bbcode_second_pass_code('', 'Upload error: 3 - Die Datei konnte nur teilweise \u00fcbertragen werden (translation: file only partially uploaded)
')

In the apache log there's the error

$this->bbcode_second_pass_code('', ' AH01630: client denied by server configuration: /usr/share/webapps/owncloud/data/.ocdata
')

And in the Chromium Javascript console I get


$this->bbcode_second_pass_code('', '
POST https://MyServerurl/owncloud/index.php/apps/files/ajax/upload.php net::ERR_SPDY_PROTOCOL_ERROR
Navigated to https://MyServerurl/owncloud/index.php/apps/files/')

I filed an Issue with owncloud and got the answer that its probaby a config issue (for some details on my server see the link)
https://github.com/owncloud/core/issues/25285
The problem is that i cant find the cause of the error.

(for privacy reasons, i replaced my server url with MyDomain )
/etc/httpd/conf/httpd.conf

After an update to Owncloud 9.0.3 the error messages read

AH01630: client denied by server configuration: /usr/share/webapps/owncloud/data/htaccesstest.txt

and:

Fehler beim Hochladen der Datei "filename":
Problem loading page, reloading in 5 seconds

[JBecker]

Found the culprit: In Apache, I've set

Protocols h2 http/1.1

instead of

Protocols h2c http/1.1

as it should be. Now everything works fine.

You're right.

The right setting is in /etc/httpd/conf/httpd.conf:

$this->bbcode_second_pass_code('', 'LoadModule http2_module modules/mod_http2.so
Protocols h2c http/1.1
H2Direct on
H2Upgrade on
')
