Connection To Local DB After Application Deployment In Fly.Io

I am Japanese, so I apologize if my English is not correct.

Thank you for your help.

We have now completed our deployment on Fly.io, but we are not able to connect to the DB properly.

The DB is created with PostgreSQL and is on Docker.

The log on Fly.io shows the following error.

We do not know the cause of the problem, etc. and would appreciate any guidance you can give us.

Thank you in advance.
