Send to Tableu Server Node - Authentication Error

[rodpereira]

Hi everyone!

I’m having trouble using the “Send to Tableau Server” node. I’m certain that the server information and my credentials are correct because other colleagues in my company use this node with no trouble.

I fill the server host and site content URL, put my credentials username and password, and when I click on “Browse” to select the datasource, the following error appears:

“Connection Failed
javax.ws.rs.ProcessingException: javax.net.ssl.SSLHandshakeException: SSLHandshakeException invoking https://serveraddress.com/api/2.8.auth.signin: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to fin valid certification path”

I’ve seen other resolution here in the forum, which involves using the command prompt to include the server certificate into KNIME JRE folder, but unfortunately I don’t have administrator privileges, so it didn’t help me.

Tableau Hyper, send to tableau server

Hi, An update from my side after a christmas break. I got it to work after a few iterations: The old path for the Tableau API that was used in KNIME 3.6 was still in my PATH variable. Removing this, helped on the old TDE version. Certificates were imported using the following steps and commands(in the windows command prompt) Open the server webpage in google chrome and export the certificates to files Open the command prompt and change path the the KNIME JRE and bin folder C:\Program Files…

Any other idea would be really appreciated. Thank you!

Guys, a collegue at work found the solution, and it is simple as removing the ‘s’ letter from ‘https’ on the host name.
If anyone is having trouble with this I hope it helps too.
