I wonder what the right approach is for using internal AI API endpoints (like LiteLLM) on self-hosted Discourse instances. I tried enabling docker bridge, container IPs, and proper SSL-terminated endpoints (to the same public IP where Discourse is hosted), but nothing works. I allowed internal host…

I solved it adding the Docker Internal Gateway IP to DISCOURSE_ALLOWED_INTERNAL_HOSTS and exposing the port on LiteLLM docker-compose.yml file: ports: - "4444:4000" Nginx points to LITELLM_IP:4000 and Discourse to GATEWAY_IP:4444 to avoid port conflicts. Then I solved the errors on M…

If you are running it on the same server, you will need to allow it via DISCOURSE_ALLOWED_INTERNAL_HOSTS env variable.

I did it on UI like I saw on a previous similar post . Tried also with the variable on my app.yml file but still getting the error. What can be wrong if my credentials are OK and I can use the API endpoint on the host? Can I debug more?

How exactly did you add it to the app.yml ? It expects either an IP or a hostname.

Well, I tested the endpoint with SSL within Discourse (app container) and it works, but not from the Discourse AI UI test. I’m using ‘OpenAI’ Provider with ‘ https://llm.mydomain.tld/v1/chat/completions ’ as URL. The credentials are OK: /var/www/discourse/plugins/discourse-ai/lib/completions/endpoin…

[이미지] satonotdead: I’m using ‘OpenAI’ Provider with ‘ https://llm.mydomain.tld/v1/chat/completions’ as URL. The credentials are OK: [이미지] satonotdead: DISCOURSE_ALLOWED_INTERNAL_HOSTS: 172.16.X.X Try DISCOURSE_ALLOWED_INTERNAL_HOSTS: llm.mydomain.tld instead then.

Already did it as I wrote before, nothing is working and I’m kindly asking how to debug more because it’s something strange. This endpoint works within the Discourse container app but not from Discourse UI as is.

I was able to get this to work by doing DISCOURSE_ALLOWED_INTERNAL_HOSTS: localhost as an environment variable to connect to my LiteLLM sidecar hosted at localhost:4000. I also have a pull request to add vertex AI auth here: FEATURE: add Google Vertex AI LLM provider - Pull Request #41350 - discours…

app.yml에 정확히 어떻게 추가하셨나요? IP 또는 호스트네임을 기대하고 있습니다.
