Data Connection failed with error: Bad Status: Unrecognized response with no error message header

Hello everyone!

 

I am facing an error, while connecting to Databricks notebook

[DataSource.Error] ODBC: ERROR [08S01] [Microsoft][Hardy] (115) Connection failed with error: Bad Status: Unrecognized response with no error message header. Status code: 502. .
 
Before that I had error that said that spark.driver.maxResultSize is not enough, so I configured it too 300g.
Does anyone knows how to fix this?
 
Thank you!
