When does this happen?

IF When using Ollama as the LLM in LlamaIndex, a query call fails with 'httpcore.ConnectError: [Errno 99] Cannot assign requested address'.

How others solved it

THEN Ensure the Ollama server is running and accessible on the expected host and port. Increase the request_timeout parameter in the Ollama constructor and implement a retry mechanism in the query execution to handle transient network issues. For local setups, confirm the service is active and bound to the correct interface.

Settings.llm = Ollama(model="mistral", request_timeout=60.0)
