I want to start the server with docker and access localhost
"Unable to access this site. Connection refused on localhost."
Will be said.

docker-compose up
Starting myapp_db_1 ... done
Starting myapp_web_1 ... done
Attaching to myapp_db_1, myapp_web_1

Probably due to "database system was shut down at 2020-09-27 08:48:28 UTC" but I don't know how to fix it. Please give me some advice.
