Console command not working

Greetings friends. New user so I apologize if this is a dumb question. Installed Docker and Portainer on my Pi4. All seems fine except when I try to enter the console for a container. After I hit connect the screen quickly flashes and the terminal does not appear. It does this on all containers (3 so far). I have searched for similar issue and have not ran into anything to try.

Any suggestions?
