[ckan-dev] Unable to upload file on CKAN

[Library IT]

Dear Jason & Tech Team,

Thanks a lot for your valuable help for CKAN.

Now I am able to upload data. But I am not able to view the Preview of CSV
file.

It giving some error : "Could not load preview: DataProxy returned an error
(Data transformation failed. error: An error occured while connecting to
the server: DNS lookup failed"

[image: Inline image 1]

When I search into Google.. I found
http://stackoverflow.com/questions/20515007/this-resource-can-not-be-previewed-at-the-moment-ckan

Local server is connected to the Internet : Is it required to live url for
preview ? or if we are able to view preview in local then is there anything
configure ?

Waiting for your reply..

Thanks & Regards,
Bhavesh
