 * BUGFIX: [vminsert](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): properly close broken vmstorage connection during [read-only state](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#readonly-mode) checks at `vmstorage`. Previously it wasn't properly closed, which prevents restoring `vmstorage` node from read-only mode. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4870).
 * BUGFIX: [vmstorage](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html):  prevent from breaking `vmselect` -> `vmstorage` RPC communication when `vmstorage` returns an empty label name at `/api/v1/labels` request. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4932).
