The [light client protocol](https://github.com/ethereum/consensus-specs/blob/v1.3.0-rc.3/specs/altair/light-client/sync-protocol.md) depends on consensus layer (CL) full nodes to serve additional data. As this is a new protocol, not all implementations are supporting it yet. Therefore, it may take several minutes to discover supporting peers, during which no log messages may be produced.
