ERR_FSPROVIDER_HTTP_CONNECTION_FAILED: HTTP connection failed

Dataiku DSS tried to connect to a HTTP server but couldn’t establish the connection.

This error can happen:

  • when trying to preview or use HTTP datasets

  • when trying to run a download recipe with HTTP sources

This error indicates that the connection could not be established. The message of the error will contain additional information.

Some common reasons for failure to establish the connection are:

  • The connection settings (host, port, …) to the server are invalid

  • The HTTP server is not running or not accepting connections

  • There is a firewall blocking connection attempts from Dataiku DSS to the HTTP server

  • The URL is incorrectly labeled as HTTPS instead of HTTP or vice-versa

Remediation

The first step for solving this issue is to go to the dataset’s or download recipe settings screen.

  • Refer to the documentation on HTTP dataset and documentation on Hive in order to get additional information on HTTP sources in Dataiku DSS.

  • Make sure that the URLs are correct

  • Try accessing these URLs in the browser

  • Try accessing these URLs using the curl command line from the Dataiku DSS server

  • Check if a firewall is blocking connections between Dataiku DSS and the HTTP server(s)
