Forbidden access to gitlab assets


Obvieusly, I’ve got a problem with Gitlab-CE. I have installed it on my Debian 8 VPS. It runs ok with only one exception. The assets of Gitlab are not loading. I tracked down that this is caused by Forbidden error to every asset file. So, I looked for gitlab files. I found them in /opt/gitlab/embedded/service/gitlab-rails (I paste this path here because I still don’t know if I installed Gitlab correctly).
Permissions for app/assets are:
drwxrwxrwx 6 root root 4096 Jan 3 2016 assets
And for the files inside:
drwxrwxrwx 2 root root 4096 Sep 10 10:04 fonts drwxrwxrwx 4 root root 4096 Sep 10 10:04 images drwxrwxrwx 17 root root 16384 Sep 10 10:04 javascripts drwxrwxrwx 6 root root 4096 Sep 10 10:04 stylesheets
And so on recursively. Probably it’s because of “root:root” permissions but I in /var/www directory this user:group configuration works fine. Also, I’ve noticed that path to “forbidden” resource linked in the website source looks like:
assets/favicon-075eba76312e8421991a0c1f89a89ee81678bcde72319dd3e8047e2a47cd3a42.ico. Where can I find cached(?) gitlab files?

Take a look in the directory /opt/gitlab/embedded/service/gitlab-rails/public/assets

Or (should be basic linux knowledge) just run:

find / -name 'favicon-075eba76312e8421991a0c1f89a89ee81678bcde72319dd3e8047e2a47cd3a42.ico' 2>/dev/null
