Clients don't update avatars and uploads from browser dont work

Possibly someone can shine some light on this:

I am really confused about the SERVICE_URL and FILE_SERVER_ROOT in de Web GUI and the FILE_SERVER_ROOT setting in the seahub_settings file…

Should one of the following be the SERVICE_URL?

127.0.0.1
127.0.0.1:8000
http://cloud.domainname.nl
http://cloud.domainname.nl:8000

And should one of the following be the FILE_SERVER_ROOT ?

192.168.2.11/seafhttp
http://cloud.domainname.nl/seafhttp

I think my setting are the reason the Clients don’t update avatars and uploads from browser dont work either

These are my setting now:

seahub_setting.py:
FILE_SERVER_ROOT = ‘http://cloud.domainname.nl/seafhttp

Web GUI:
SERVICE_URL http://cloud.domainname.nl
FILE_SERVER_ROOT http://cloud.domainname.nl/seafhttp
