EthStaker

My worst fear happened last night. After 677 days since my last proposal, I got an opportunity, and my node missed it.
Trying not to rage-quit the solo staking game, let's figure out what wen wrong:
- No missing attestation, I usually get alerts when I miss attestation and go fix it. I wrongly assumed that healthy attestations meant healthy validator.
- Nimbus version 24.12.0 (dappnode package 1.0.16, only 3 weeks late from the "medium-urgency" update)
- No errors in the logs. Only a casual warning: "Block could not be sent from validator that is also managed by the beacon node"

Looking into the log history, it turns out a similar warning appeared for attestations as well: "A validator client has attempted to send an attestation from validator that is also managed by the beacon node"
I mean what the f* is this supposed to mean?

Upgraded Nimbus to the latest version (no config change). Warnings are gone. See you in 2 years.

This sounds like a bug. I have also had something happen and discovered a bug in the CL client I was using. Definitely contact the client team and share logs with them.

This can definitely help improve the client and also provide clarity to you about what happened.
