When does this happen?
IF Ollama call intermittently returns HTTP 400 error with 'unexpected server status: 1' during LLM generation in LangChain.
How others solved it
THEN Wrap the LangChain chain with `.with_retry()` to automatically retry on transient failures. Alternatively, use `.with_fallbacks()` with a duplicate chain. This mitigates sporadic errors without changing the underlying model.
rag_chain = prompt | llm | StrOutputParser() rag_chain = rag_chain.with_retry()
