Hello everyone,

I'm experiencing an issue where my validators haven't proposed a single block for about a month, which is highly unusual. I've checked the logs and noticed that even when it's my turn to propose a block, the blocks don't seem to be credited to my validator. Here’s a snippet from my log:

Mar 29 07:20:17.001 INFO Some validators active slot: 8739399, epoch: 273106, total_validators: 15, active_validators: 13, current_epoch_proposers: 1, service: notifier Mar 29 07:20:23.001 INFO Requesting unsigned block slot: 8739400, service: block Mar 29 07:20:23.887 INFO Received unsigned block slot: 8739400, service: block Mar 29 07:20:23.948 INFO Publishing signed block signing_time_ms: 60, slot: 8739400, service: block Mar 29 07:20:24.211 INFO Successfully published block slot: 8739400, graffiti: Some(""), attestations: 65, deposits: 0, block_type: Blinded, service: block Mar 29 07:20:29.000 INFO Connected to beacon node(s) synced: 1, available: 1, total: 1, service: notifier Mar 29 07:20:29.000 INFO Listening for doppelgangers doppelganger_detecting_validators: 2, service: notifier

As per the log for slot 8739400, it was my validator's turn, and it signed and published a block. However, the block’s proposer listed on the explorer is not my validator (https://mainnet.beaconcha.in/slot/8739400).

This issue started occurring after I updated geth, lighthouse, and mea-boost for the Dencun upgrade. I suspect this might be a configuration error on my side, but I can't seem to pinpoint the exact issue.

Has anyone else faced a similar problem? Any insights or suggestions on what might be going wrong or how to troubleshoot this would be greatly appreciated!

Thank you!
