Docker Postgres PGAdmin4 MacOS - pgadmin4 does not show docker Postgres volume data after restart - postgresql

Question

I recently had to restart my machine, thus shut down my docker container and server connections. After restart PGAdmin4 no longer shows docker volume data, however my application is still able to access the docker volume data. I'm able to log in to my db as user postgres, though no tables show in the db. PGAdmin4 on 5050:5050, Postgres on 5432:5432, app on 5000:5000. I'm able to log into the db via PGAdmin while the container is paused, which wasn't the case before, finding it hard to understand why.
I've got a docker-compose file like so:
version: "3.7"
services:
postgres:
container_name: postgres
restart: always
image: postgres:12.2
environment:
- POSTGRES_USER=${POSTGRES_USER}
- POSTGRES_PASSWORD=${POSTGRES_PASSWORD}
- POSTGRES_DB=${POSTGRES_DB}
volumes:
- flask-app-db:/var/lib/postgresql/data
ports:
- 5432:5432
networks:
- pgnetwork
pgadmin4:
container_name: pgadmin4
restart: always
image: dpage/pgadmin4
environment:
- PGADMIN_DEFAULT_EMAIL=${PGADMIN_DEFAULT_EMAIL}
- PGADMIN_DEFAULT_PASSWORD=${PGADMIN_DEFAULT_PASSWORD}
- SERVER_PORT=${SERVER_PORT}
volumes:
- pga4:/var/lib/pgadmin
ports:
- 5050:5050
networks:
- pgnetwork
dplio:
container_name: dplio
restart: always
build:
context: .
dockerfile: Dockerfile
environment:
# MY_ENV_VARS
ports:
- 5000:5000
volumes:
- .:/dplio
networks:
- pgnetwork
depends_on:
- postgres
networks:
pgnetwork:
driver: bridge
volumes:
flask-app-db:
name: flask-app-db
pga4:
name: pga4
My terminal output when the containers are run:
Starting postgres ... done
Starting pgadmin4 ... done
Starting dplio ... done
Attaching to pgadmin4, postgres, dplio

I thought to try a pg_restore from the docker volume to host but that doesn't seem to make sense as a potential solution, I think it's a connection issue between the docker container and my host machine, not a data loss problem.
I set PGAdmin4 port to 5050 in the browser, though it worked fine without that before I restarted.
I tried visiting http://localhost:5050/?key=xxxxxxx http://0.0.0.0:5050/?key=xxxxxxx and http://1270.0.0.1:5050/?key=xxxxxxx, the key taken from ~/.pgAdmin4.XXXXXXXXXXXXXXXXXX.addr same issue.
I've tried removing my docker app image and rebuilding it, too.
Can anyone let me know what I'm missing? A step by step for shutting down server/container/network connections and restarting would be super helpful!
If you need more info let me know.
Thanks!
