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…

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…

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.

Como usar endpoints de IA internos?

Se você estiver executando no mesmo servidor, será necessário permitir o acesso por meio da variável de ambiente DISCOURSE_ALLOWED_INTERNAL_HOSTS.
