Hello,

I am currently facing a strange error. I am building a pipeline to keep my Tableau Personal Access Token (PAT) active, as Tableau's policy states that the PAT can expire after 14 days of inactivity. The purpose of this pipeline is to ensure that the PAT remains active. However, I received an error when I ran the pipeline.

com.streamsets.pipeline.api.StageException: HTTP_32 - Error executing request. HTTP-Status: NULL Reason: java.net.ConnectException: Connection refused

Aside from StreamSets, I was able to test the connection using the PAT token in Postman, and it worked fine. I tested a Python script that successfully authenticates with the Tableau API. The Tableau API appears to be working fine when I use it.

As for the network, I don't use a proxy for StreamSets. Tableau Server doesn't have any traffic restrictions or any IP addresses on a blacklist. I'm wondering if it has something to do with the engine's configuration.
