mysql-workbench (no replies)

I have a brand new mysql 8 installation on Ubuntu. I'm able to connect with a simple:
>mysql
(no parameters).
A \s indicates the connection is over socket and gives me the location of the .sock file. and other information
(e.g. Server version: 8.0.19-0ubuntu0.19.10.3 (Ubuntu)
When I try to connect to the server using mysql-workbench I get the following error:
Your connection attempt failed for user 'root' to the MySQL server at localhost:NULL
Access denied for user 'root'@'localhost'

Any suggestions? Could this be because Ubuntu is not officially supported by mysql-workbench?
