Sometimes you get the same message as the title question:

This resource can not be previewed at the moment.

But when you click on the “Click here for more information”, It says:

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:///dataset/c3ce226b-73bd-4b06-9d1b-ffea13d5f770/resource/580fb05f-6d86-4748-aac7-560b904a208f/download/foo.csv)

In this case, probably the datapusher plugin is not working. First follow the instructions for datapusher in CKAN manual. If you already did this or you installed CKAN from a package, check the CKAN configuration in production.ini (development.ini) file. A small check list to solve the problem:

• add datapusher in "ckan.plugins"
• set "ckan.site_url"
• set "ckan.datapusher.url"
• check Apache/nginx server logs (/var/log/apache2/datapusher.*.log, /var/log/apache2/ckan_default*.log)
