Hello all,

I hope I can get help here.
My issue is very similar to this one:
https://forum.owncloud.org/viewtopic.php?t=35110 and I already try the 2 links from this topic but they didn't work for me.
Any other ideas ?
Maybe I just missed something in my Nginx conf ...

      location /owncloud {

    proxy_pass http://domain.com/owncloud;
