1. diffgram works well for 2 days after installation(on docker in cloud) but then when i try to log in the diffgram website, it shows error below mentioned

error: { "message": "Service is unreachable. Please check the connection to the http://default:8080 service.", "port": 8080, "service": "http://default" }
server: 503. Service unavailable. Are all services up?

2. I checked the container. db migration and minio/mc container had exited. in this, minio is used for creating bucket and we configured to create bucket in aws so i hope it will not create any error related to that.

3. db migration shows postgres is up but docker logs of postgres shows below error.

2024-11-18 07:19:38.530 UTC [308696] FATAL: database "diffgram" does not exist

4. I can see that volume is located inside the db of the yaml file. But why does this error persist?
   

5. In the container of diffgram/default:latest python3 shows below mentioned error
