I'm interested in the reason why you have chosen to install such an outdated version of ownCloud? If you browse on:

you can see that ownCloud 10.0.7 is the latest available version. I think it doesn't make any sense to install anything else then this version on a fresh setup.

i did the following search:

https://central.owncloud.org/search?q=%22No%20basic%20authentication%20headers%20were%20found%22

and found:

https://central.owncloud.org/t/no-basic-authentication-headers-were-found-message/819

It seems to be that this is caused by some insufficient server configuration.

Because the hosting provider refuses to upgrade libxml2 from 2.6.30 to at least 2.7.0 right now.
It is also the version of ownCloud provided by the hosting provider as quick install.
PHP would be available in latest versions.

I will check that with the hosting provider.

I've tried https://owncloud.somedomain.com/remote.php/webdav which shows the HTTP basic-auth popup, accepts the credentials entered and responds with "200/OK "This is the WebDAV interface. It can only be accessed by WebDAV clients such as the ownCloud desktop sync client."". Also WebDAV from a cli client or webDAV browser on the computer work fine.

Accessing OCS https://owncloud.somedomain.com/ocs/v1.php/cloud/user?format=json directly in the browser keeps sending the HTTP basic-auth popup (I did not add the "OCS-APIREQUEST: true" header manually). This is the URL used by the Android client.

Mhhh, ok. Understand the reason. :slight_smile:

But i don't think that it is a good idea to run ownCloud 8.2 on a public facing hosting provider. Besides the requirement for the libxml2 (which is probably there for a reason) 8.2 reached its end-of-life nearly one year ago according to https://github.com/owncloud/core/wiki/Maintenance-and-Release-Schedule

From what i know this means you won't get any bugfixes, security updates or support for this version.

Addition:

I did a short research on the issue tracker about that and found:

If i'm understanding this correctly the requirement indeed was already there for older versions of ownCloud. Only the newer versions had added a check for it.
