Hey @KristiLogos 

I had a little search online and found this which may be useful:

https://stackoverflow.com/questions/79236996/pyspark-jdbc-connection-to-netsuite2-com-fails-with-fai...

in short it seems that a token based connection is not possible with spark/JDBC as the connection made is single use: and spark is effectively making two connections - one for metadata and one for data.

The author managed to solve their issue by swapping over to username/password authentication. Even if it’s not viable long-term, could you try making a connection this way instead, to confirm that is the issue?
