Key points

  1. Note the action and the time of the issue, then check Activity.
  2. For the native Companion, check the local network. For the Web Companion, also check Internet connectivity and HTTPS transport; the PC remains the unlock authority.
  3. If a QR code expired, generate a new one from the PC.
  4. If a method is unavailable, the password remains usable.
  5. Advanced mode exposes local technical state without transmitting anything outside.
