Getting stuck at "Create ssh tunnel for port 8000" step for setting up airbyte at Amazon EC2 following the docs

[ggg]

I tried setting up AirByte on Amazon EC2 following the docs but can’t get the last step (creating ssh tunnel for port 8000) to work:

When I type that command and press enter nothing happens and the terminal freezes. Please help.

This is my port settings in EC2. Please suggest if something’s wrong…
