I try to connect Dremio EE 21.8.3 Software (not cloud release) using following method [Connecting to Dremio Using Apache Arrow Flight in Python | Dremio](https://www.dremio.com/blog/connecting-to-dremio-using-apache-arrow-flight-in-python/).  
I get following error … which in fact is an empty message.
