Recommended action: Start Qdrant (e.g. docker run -p 6333:6333 qdrant/qdrant) and make the URL reachable from where the extension host runs. Option: Start Qdrant (e.g. docker run -p 6333:6333 qdrant/qdrant) and make the URL reachable from where the extension host runs. [evidence: official_recommended_action] Applies when: Starting indexing with a local Qdrant URL Steps: 1. curl <qdrantUrl>/collections from the extension host 2. Fix URL/API key 3. For Remote/WSL, use an address reachable from the remote host Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
