I found a similar closed issue that might be relevant to your problem. The issue was about the reranking model not taking effect, and it was resolved by ensuring that the reranking model settings were correctly configured in both the default settings and the knowledge base settings. It was also important to verify that the reranking_mode and reranking_model configurations were correct and that there were no authorization errors or misconfigurations in the Docker setup. Checking the logs for any errors or warnings was also recommended ^[1].
