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](https://llm.mydomain.tld/v1/chat/completions)’ as URL. The credentials are OK:

/var/www/discourse/plugins/discourse-ai/lib/completions/endpoints/open_ai_shared.rb:28:in 'DiscourseAi::Completions::Endpoints::OpenAiShared#perform_completion!'
/var/www/discourse/plugins/discourse-ai/lib/completions/llm.rb:214:in 'DiscourseAi::Completions::Llm#generate'

pitchfork-0.18.2/lib/pitchfork/soft_timeout.rb:94:in 'block (2 levels) in Pitchfork::SoftTimeout#create_timeout_thread'
pitchfork-0.18.2/lib/pitchfork/soft_timeout.rb:93:in 'Array#each'
pitchfork-0.18.2/lib/pitchfork/soft_timeout.rb:93:in 'block in Pitchfork::SoftTimeout#create_timeout_thread' 

```

It’s strange, and I’ve been trying to get it done for weeks.

Already tried this:

**EDIT 1:** `DISCOURSE_ALLOWED_INTERNAL_HOSTS: 172.16.X.X` _(LiteLLM container IP, 127.0.0.1 and the SSL terminated LLM domain host I understand is not requested to be here)_

**EDIT 2:** And I see the same 500 error when trying to enter to configure my MCP server (MCP discourse-ai tab configuration).
