N8n + Ollama: AI Agent returns "Failed to receive response" even though models load fine

Hi all,

I’m running n8n locally on Olares OS and I’m hitting a wall with the Ollama integration in an AI Agent workflow.

Setup:

  • n8n running on Olares OS
  • Ollama Chat Model node connected to an AI Agent node (with Simple Memory)
  • Workflow: When chat message receivedAI AgentOllama Chat Model

The problem:
Every time I submit a message in the chat, I get Error: Failed to receive response. The Logs panel stays empty — no error details there either.

What I’ve already checked:

  • The connection to Ollama works — in the Ollama Chat Model node I can see and select the available models, so the Base URL is reachable.
  • “Allowed HTTP Request Domains” is set to All.
  • The credential is configured (Base URL + API key).

So the model list loads correctly, but the actual chat generation always fails with “no response.”

Questions:

  • Has anyone run into this on Olares specifically?
  • Could this be a timeout / resource issue with CPU inference, or something about how Olares networks the n8n and Ollama containers?
  • Is there a recommended Base URL / config for reaching Ollama from the n8n container on Olares?

Any pointers appreciated. Happy to share more config details. Thanks!

Thank you for bringing this to our attention!

We have confirmed that this was a bug with the n8n webhook, and it has now been fixed. Could you please update your n8n and give it another try? If anything else pops up, just drop a comment below and we can keep the discussion going.

It’s working now! Thank you very much, you guys are awesome! :heart_eyes:
