loomio-worker | could not connect to server: Connection refused

Hello!

I've successfully installed loomio-deploy following github loomio-deploy instructions.

The server is an Ubuntu 18.04.

The app worked yesterday before setting the crontab. I saw the main loomio page.

Today the app and workers are failing to start due to pg connection refused.

I need some help with that issue. Thanks.

Here are some logs:

I know I can connect to the pg server:

~/loomio-deploy# /snap/bin/docker exec -it loomio-db psql -h 172.17.0.3 -U postgres
psql (12.2 (Debian 12.2-2.pgdg100+1))
Type "help" for help.

postgres=# exit
