"No working beacon nodes available" logs on validator client

[canbal99]

Describe the bug I am running 2 validators on prater network (on rpi4 8GB booting with 1TB USB SSD). My Beaconchain and Validator processes are separate. Even if there is no problem with my BC client, I continuously see this error on validator client. "No working beacon nodes available" NOTE: Validator is attesting properly during that time. No problem with performing tasks.

I also have a script which runs periodically (every 15 or every 30 minutes) to check health of my processes. Following eth api requests are executed using curl command:

• node/version
• node/peer_count
• node/syncing
• debug/beacon/heads (replaced with beacon/headers/head)

To Reproduce It always happens in my setup. Might be related with api requests and/or running a separate validator.

Hi - since this report, we've addressed a large number issues in the VC-BN communicaiton protocol - I would expect this has been fixed as I'm unable to reproduce - do give v22.6.0 a whirl.

Closing as VC-BN connectivity has thoroughly been reviewed since.
