Hi @xqin-ls! I'm Dosu and I’m helping the ragflow team.

The Redis queue warning (RedisDB.queue_info rag_flow_svr_queue got exception: no such key) is not related to changing the HTTP port. This message just means the expected Redis queue doesn't exist yet—usually because no tasks have been produced or processed. It's a normal startup warning and doesn't indicate a real error unless your tasks are stuck or failing to process.

If you want to clear the warning, upload and parse a file into a knowledge base; this will create the necessary Redis queue and the warning will disappear (details). If you're not seeing any actual failures, you can safely ignore this message (details). If task processing is stuck, check that Redis is running and accessible from inside your container (for example, with redis-cli -h redis -p 6379 ping) (details).

The HTTP port and Redis queue logic are completely independent in the codebase and config (details).

To reply, just mention @dosu.

@dosu.
After I run the command docker exec -it ragflow-redis redis-cli -h redis -p 6379 -a xxxx ping, I could get Pong answer, but I still can't connect the ragflow-server from web.

Your Redis connection is working, but web access to ragflow-server depends on Docker port mappings and nginx proxy settings, not Redis. According to your logs, ragflow-server is running on port 9380 inside the container, and nginx proxies web requests on port 80 to it.

To access the web UI, you should connect to the host port mapped to container port 80 (nginx), not directly to 9380 unless you want the raw API. If you changed the external port (for example, to 3080), make sure your Docker Compose or run command includes a mapping like 3080:80 for the ragflow-server service. If you want to access the backend API directly, map your desired host port (e.g., 3080) to container port 9380.

Check your firewall and network settings to ensure the relevant port (80, 3080, or 9380) is open and accessible from your client machine. If you still can't connect, please share your current Docker Compose or run command (especially the ports section), the exact URL and port you are trying to access in your browser, and any error messages you see. This will help pinpoint the issue.

For reference, see the official port mapping and nginx proxy setup here and here. Common issues include mismatched port configs between docker-compose.yml, .env, and service_conf.yaml.template, or missing firewall rules details.

To reply, just mention @dosu.

[onestardao]

this is actually a classic infra failure caused by improper startup order — your ragserver likely tried to pull from Redis before the queue was actually ready or namespaced properly.

we’ve categorized this issue in our open-source ProblemMap under:

• No.8: deployment-deadlock
• No.9: bootstrap-ordering
• No.10: predeploy-collapse

our fix involves semantic startup sequencing and runtime safeguards — it's open-source under MIT, and also received a star from the creator of Tesseract.js.

if you need the repo or implementation details, feel free to ask.

Hi, @xqin-ls

Try:

$ docker exec -it ragflow-redis /bin/bash
# In container
$ redis-cli -a infini_rag_flow
# In redis-cli
XGROUP CREATE rag_flow_svr_queue rag_flow_svr_task_broker $ MKSTREAM

This issue has been fixed in #9223. But you can still have a try to fix it by your own.

Cheers.
