Default env variables mix binding IP addr with public URL #168
Description
If the default env variables are used, then:
CAT_HOST = 0.0.0.0
CAT_PORT = 8080
CAT_SERVER_URL = <CAT_HOST>:<CAT_PORT>
CAT_UI_DOMAIN = <CAT_HOST>:<CAT_PORT>
With these default values, after a login the browser will try to access 0.0.0.0:8080, and fail.
