Connect Langfuse to RAGflow

[jacksonasl-07]

Describe your question

I have already generated SK and PK, and RAGFlow and Langfuse are both running in the same Docker environment. However, when I try to connect RAGFlow and Langfuse, I get a ConnectError('[Errno 111] Connection refused'). Why is this happening? Do I need to create an env file to store PK and SK?

Langfuse Cloud or Self-Hosted?

I can’t find any information in the available sources about connecting Langfuse specifically to RAGFlow, nor about how RAGFlow should be configured to talk to a self‑hosted Langfuse instance.(1)(2)(3)

Because of that, I can’t say from these sources why you are seeing ConnectError('[Errno 111] Connection refused'), nor whether RAGFlow expects PK/SK via an env file or some other configuration.(1)(2)(3)

Check out these potentially useful sources: Troubleshooting & FAQ, Local Deployment (v2, docker compose), Scaling.

If you’d like, I can try to give a general (non‑Langfuse‑specific) answer based on typical Docker networking and API key usage patterns.

@Yeon1007 How did you configure RagFlow to send traces to Langfuse? Can you establish a network connection to Langfuse from your instrumented application outside of RagFlow, e.g. using the Langfuse SDK?
