502 - Failed to verify validator signature

[dannliuu]

Hey all, I've been having some issues on spinning up mev-boost on a goerli testnet machine with two validators (64 goETH) being staked. Both the validators can be seen using the following links:

https://prater.beaconcha.in/validator/0xa26f92f0a0482db5b2d5c697058599587045b522a31ed22f392bb4d1be58b840cc5f66af8032db5723672a733d1593a0

I see the following logs on my machine running geth v1.10.23 / prysm v3.0:

My validator routinely shows this upon each epoch:

Any thoughts?

The error message inside this shows that the relay couldn't verify the signature:

failed to verify validator signature for 0xa26f92f0a0482db5b2d5c697058599587045b522a31ed22f392bb4d1be58b840cc5f66af8032db5723672a733d1593a0

@metachris What could be causing this error? Apologies if I'm not getting the whole picture of this. I have been using the Flashbots & bloXroute relay and they appear to be still producing the error.

It appears that I was missing the "--goerli" flag on my validator. It may be useful for people to note that you must have this flag if you are using somer-esat's testnet systemd settings for prysm.
