[Pkg-owncloud-maintainers] Bug#886395: /usr/bin/owncloud: fails to connect to the server

[Nicolas Évrard]

Package: owncloud-client
Version: 2.4.0+dfsg-1
Severity: important
File: /usr/bin/owncloud

Dear Maintainer,

I rebooted my computer after upgrading to the newer kernel and my
owncloud client suddenly stop connecting to my server.

When I use the logging window here are some of the network error I
have:

    QNetworkReply::NetworkError(ServiceUnavailableError) "Error transferring https://xxxx/remote.php/dav/files/yyyy/ - server replied: " QVariant(int, 503)

The 503 HTTP Error seems strange as I can access the web interface of
nextcloud through firefox. When I try to reach the aforementioned URL
with firefox I've got a message telling me that I reached a WebDAV
interface which indicates that everything is normal.

I also have this error:

    QNetworkReply::NetworkError(ServiceUnavailableError) "Error transferring https://xxxx/status.php - server replied: " QVariant(int, 503)

But when I use curl to fetch this page I receive the expected JSON:

    {"installed":true,"maintenance":false,"needsDbUpgrade":false,"version":"12.0.4.3","versionstring":"12.0.4","edition":"","productname":"Nextcloud"}
