I have setup geth and lighthouse on sepolia.

Geth is fully synced and says Beacon client online, but no consensus updates received in a while. Please fix your beacon client to follow the chain!

Lighthouse starts fine. Is listening to 8551 port as evidenced through sof -i :8551

Geth is also having txpool and block transaction, but still lighthouse blocks are empty:

slot: 4398150, block:    …  empty, epoch: 137442, finalized_epoch: 132606, finalized_root: 0x167b…3004, exec_hash: 0x7d4b…6bc4 (verified), peers: 6, service: slot_notifier

I know for sure tx are there as I can see on etherscan sepolia. What could be wrong? I have spent a day headbanging against this. Any help is deeply appreciated!

These are geth startup logs:
