Start by reproducing the failure in the Windows Electron environment using the configured Readeck base URL and API key, then trace the save-to-Readeck request and its error handling. Check the reverse-proxy and WebSocket setup described in the report. Done means articles save successfully and the failure path has coverage or a clearly verified fix.
