Owncloud desktop client broken in use with nextcloud

lex · August 2, 2016, 8:10am

I am opening a new thread in a follow up to this conversation Problems installing @ webhoster - #29 by tflidd , because after everything else seems to be working one problem remains consinstent:

the mac os x client for own cloud does (in my case) not work with nextcloud.

did a fresh install on the hosted webspace of nextcloud, no beta version, latest stable version of 9xxx.

we repaired all the rights, installed a tmp directory. error messages now appearing are minor and have also been appearing with owncloud.

when i use this very domain with owncloud, the desktop client will log in the account and start transfer.

when i use this domain with nextcoud, i will always always get an error message that the server doesnt allow access. (see image)

When i follow the link to login with the same passwort / username via webbrowser, i will log into nextcloud with no problems.

also, no error is visible in the log from the login attempt.

Do your logs tell you anything?

Don´t think so, as I tried to point out, there does not seem to be ANY log entry which is related to the trial to log via the desktop client.

ooops, update: no entries when logging for “errors”, but changing to “log all things”, i got the following message:

Exception: {“Message”:“HTTP/1.1 401 No ‘Authorization: Basic’ header found.

Webhosters Support wrote me that there are some files missing, where the system wants to write to user.ini, which doesnt seem to exist:

Wir können Ihnen bestätigen, dass es serverseitig kein Problem diesbezüglich besteht. Wie bereits mitgeteilt, haben wir die in dem Forum beschriebene Direktive mod_rewrite in der .htaccess eingefügt haben. Die eigentliche Fehlermeldung sagt aus, dass Owncloud das Upload Limit in /kunden/XXX/kumo/tmp/oc_tmp_Ur5hjg-folder/.user.ini schreiben will. Die Datei existiert nicht.

Die folgendene Fehlermeldung besagt, dass die Datei /kunden/XXXXX/kumo/.user.ini in der /kunden/163850_80799/kumo/lib/private/integritycheck/checker.php aufgerufen wird:

Error PHP copy(/kunden/163850_80799/kumo/.user.ini): failed to open stream: No such file or directory at /kunden/XXXX/kumo/lib/private/integritycheck/checker.php#189

Diese .user.ini Datei existiert auch nicht.

Please check the configuration of your apache or nginx installation. I had the same error a few months back when it was still just owncloud and solved it by checking my nginx configuration against the documentation. I do not know what changed in the requirements.

This link might help you though:

In short, check the rewrite rule if you are using Apache. Or similar configuration settings for nginx.
The link says something about self signed certificates, and OS X I had it on Ubuntu 16.04 with Lets Encrypt certificates, but I am fairly certain that will give you the needed hint. If you are running Apache, check your .htaccess

I hope that helped.

Finally!!! I am able to log in, thanks…

.htaccess now looks like this:

DO NOT CHANGE ANYTHING ABOVE THIS LINE

RewriteEngine On
RewriteBase /
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
ErrorDocument 403 //core/templates/403.php
ErrorDocument 404 //core/templates/404.php

Header always set Strict-Transport-Security “max-age=15552000; includeSubDomains; preload”

Strangely enough, i will still get an alert “https is not configured correclty, set htts… etc”

But just to keep going in the right direction: when I log in now, I will see another error message in the logs - should I do anything about this?

Please see this thread for DAV configuration, and your error message:

as well as the Server Configuration for nextcloud with apache:

I have asked support from my webhoster about this and they actually tell me its a known bug in owncloud/nextcloud and the error message doesnt really pose any problem, can be switched off - correct?

(sorry don’t have more time to read the details), you’ve probably tried the following tips of the old FAQ:
