Hi,  
I have a PostgreSQL deployed using docker in my laptop. I am able to access PostgreSQL at 0.0.0.0:5432 from my laptop. But I am not able to connect to this PostgreSQL instance from Dremio university lab.

@ann What are the source values (minus password) you have given? Is there an error stack on the Dremio coordinator’s server.log? Have you entered the Dremio coordinator IP on the pg\_hba.conf file?
