Unable to log in to owncloud hosted on private NAS

This is unlikely to be because of the self-signed certificate. Self-signed certificates are correctly handled in webbrowser-app, when accessing a site using one of those you should see a warning screen, with two buttons: [back to safety] [proceed anyway]. If you choose to proceed anyway, the browser will let you browse the site, and will display a broken red lock in the address bar (as shown in your screenshot).

Can you please reproduce the issue and attach the log file for webbrowser-app. You will find it on your device at:

    /home/phablet/.cache/upstart/application-legacy-webbrowser-app-.log

I attached the log you requested.
Please note that the screenshot is taken from the browser-app in 15.10 as it shows the same behaviour as the phone app.

Thanks for your support.

The following messages on the javascript console look suspicious:

Could it be that your owncloud setup is incomplete, thus preventing you from logging in? Can you log in to it from another browser?

Hi Olivier,

I can log in normally using Firefox.
It even works when I use an unencrypted connection.

This is why I first tought of a certificate issue in the first place.
(Firefox is asking me to accept the certificate, webbrowser-app does not)

This is weird. You’re saying webbrowser-app is not warning you about the self-signed certificate?

Do you get a warning when you browse to https://self-signed.badssl.com/ ?

Thanks Laryllan for providing a test account/server, I’ve managed to reproduce the issue. When visiting the owncloud web interface, I am getting the self-signed certificate warning page as expected, and if I choose to proceed anyway, the page loads, but a lot of its subresources are not loading correctly.

I’m seeing e.g.:

GET https://*******.spdns.de/owncloud/core/css/mobile.css?v=xxxxxxx net::ERR_INSECURE_RESPONSE
GET https://*******.spdns.de/owncloud/core/vendor/jquery-ui/themes/base/jquery-ui.css?v=xxxxxxx net::ERR_INSECURE_RESPONSE
GET https://*******.spdns.de/owncloud/index.php/core/js/oc.js?v=xxxxxxx net::ERR_INSECURE_RESPONSE

…among many other errors, which in turn trigger errors like:

  Uncaught ReferenceError: jQuery is not defined
  Uncaught ReferenceError: OC is not defined

It looks like accepting the self-signed certificate doesn’t make oxide trust it for loading subresources. Need to investigate whether it’s a bug in oxide, or in the way webbrowser-app uses it.

Ha, this is in fact a known bug in oxide: bug #1503035. I’m going to mark this one a duplicate, and will bump the importance of the other one.

Thank you Olivier.
