Same problem, the Jina sundently stop working, change it to local embedding for a temporary fix for now.

It's like it cannot even communicate with the Jina API. Looking at the API usage on my dashboard there are no queries or calls being made by the plugin...

You may want to see #412 - after fixing this it seems to work with the external reranker and embedding...

Thanks for the report! The setup wizard's probe script is failing silently and incorrectly concluding that your API doesn't support rerank — this is a probe bug, not a key issue.

Workaround: skip the wizard and configure manually:

"retrieval": {
  "rerank": "cross-encoder",
  "rerankProvider": "jina",
  "rerankApiKey": "YOUR_JINA_KEY",
  "rerankModel": "jina-reranker-v3",
  "rerankEndpoint": "https://api.jina.ai/v1/rerank"
}

This bypasses the probe entirely and should work correctly with a valid premium key. The probe script fix is being tracked separately.
