After login, display [404 not found]

Hi

set up redash now.

redash:v8.0.0
OS:Amazon Linux2
docker:18.09
docker-compose:1.24.1

I install and setup redash following this(https://redash.io/help/open-source/dev-guide/docker)

After make Admin User, when i log in redash, displayed 404.

Do you know the reaon why?
