3 weeks ago I found a couple of similar discussions that might be relevant to your issue:
-
Connection error: request error, status_code: 503 - This discussion is still open and might provide insights into connection issues similar to what you're experiencing [1].
-
About docker-compose deployment issues - This is another open discussion that could be related to deployment issues in a Docker environment [2].
Regarding the error you're encountering, it seems to be related to a database connection issue with PostgreSQL. Here are a few things you might want to check or try:
- Ensure that your PostgreSQL server is running and accessible from the Dify application.
- Check the PostgreSQL logs for any errors or warnings that might indicate why the connection is being closed unexpectedly.
- Review your PostgreSQL configuration settings, especially those related to connection limits and timeouts. You might want to adjust
POSTGRES_MAX_CONNECTIONSand other related settings to ensure they are appropriate for your workload [3]. - Consider enabling SQLAlchemy's connection pool pre-ping feature by setting
SQLALCHEMY_POOL_PRE_PINGto true, which can help detect and handle stale connections [4].
These steps might help in diagnosing and resolving the issue.

Steps to reproduce
I use dify with postgres, but when I made an api connection, very often it breaks and doesn't answer anything.
I looked up and dify doesn't ever get the data, this is the error that I get
File "/app/api/.venv/lib/python3.10/site-packages/sqlalchemy/engine/default.py", line 941, in do_execute cursor.execute(statement, parameters) sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.
✔️ Expected Behavior
no error with the api connection
❌ Actual Behavior
api doesn't get any data
