Fetch Failed (on windows native install of Flowise & ollama)

[vannoo67]

I am trying to follow Leon van Zyl's video 'Build a FREE AI Chatbot with LLAMA 3.2 & FlowiseAI (NO CODE)' https://www.youtube.com/watch?v=lJOZiRoZNJw

I have managed to set up the Document Store (using a DOCX loader and Faiss Store Provider) and the Chatflow using Conversational Retrieval QA Chain, ChatOllama, Buffer Memory and Vector Document Store nodes.

When I try to test the chat, any prompt returns "fetch failed".
It seems that there is a problem accessing Ollama. I have both Ollama (v0.3.12) & Flowise (v2.1.2) installed natively (not Docker) on Windows 10. I have Ollama running on the default port. If I hit http://localhost:11434/ I get "Ollama is running". Note: I have successfully accessed Ollama using Open WebUI (Open WebUI is not running while I did these tests).

Any suggestions would be gratefully received.
