Trying to create a new Postgres connection - postgresql

Question

I implement a java microservice application deployed under a docker using postgres as data base. I am on MAC. Yesterday I created successfully a connection on DBeaver using the host of my MAC : 192.168.1.73. Today, I cannot connect with this host.
I tried $ telnet 192.168.1.73 5432 and had the following output
Trying 192.168.1.73...
telnet: connect to address 192.168.1.73: Connection refused
telnet: Unable to connect to remote host
What can I do ?
EDIT
I run docker-compose.yml
here is the extract for the data base
database:
image: postgres:9.5
ports:
- "5432:5432"
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=Esprit292948
- POSTGRES_DB=immo_db_local
Here is the begining of docker-compose.yml. I voluntarelly hid the details

Answer 1

I didn't pay attention, there was an error message
Name does not resolve
So I added "apk add bind-tools" to the docker files to get logs, according to this post : Docker Compose and Postgres : Name does not resolve
After which I had another error
Docker error : no space left on device
So according to this post Docker error : no space left on device : I run
docker system prune
And then, I succedded to connect with DBeaver
