What I Did

I followed all the steps described till this part

git clone https://github.com/dremio-hub/dremio-flight-connector.git
mvn clean install

move the plugin (the shaded jar that is created by maven) to dremio/jars When I try to connect I am getting this error, can someone guide me how to fix this problem.

Hi @JemiJey can you check the Dremio logs for errors or messages from the flight plugin. The client error indicates wrong password or an inaccessible flight port
