[ckan-dev] Resource preview error on non-root ckan

Thu Jul 3 11:58:14 UTC 2014

Hi,

I have installed ckan 2.1.1 with datapusher on Ubuntu 12.04. Running the whole thing works fine as root (example.com) through apache and proxy by nginx.
I want to serve CKAN on a non-root URL (example.com/ckan). I made the following settings:

 - Changed 'WSGIScriptAlias / /etc/ckan/default/apache.wsgi' in 'WSGIScriptAlias /ckan /etc/ckan/default/apache.wsgi' in  /etc/apache2/sites-available/ckan-default 

 - Changed 'location / { ' in 'location /ckan { ' in  /etc/nginx/sites-available/ckan 

 - Changed 'proxy_pass http://127.0.0.1:8080' in 'proxy_pass http://127.0.0.1:8080/ckan' in  /etc/nginx/sites-available/ckan 

 After this settings ckan is accessible on example.com/ckan. When creating new resource , upload is execute ok, download new resource is ok. There is an error that appears when I try to view the resource I just uploaded 

 "This resource can not be previewed at the moment.
 Could not load preview: DataProxy returned an error (Data transformation failed. error: An error occured while connecting to the server: DNS lookup failed for URL: http://example.com/ckan/storage/f/2014-07-03T10%3A55%3A34.762Z/test.csv"

 Also, in the datapusher.error.log there is an error message:

 Any help would be appreciated.
 Thanks in advance,
