event stream being closed error

Validator *** Error while connecting to beacon node event stream

• probably doesn't need to be an error, its expected that this may disconnect/reconnect occasionally
• depending on how we're setup, might be able to raise an info / warning on disconnect and only error if we can't reconnect for a period of time...
