Sorry, I should have been more clear. When I say I’d call my rov at 3:00am, I meant MY rov, the one I daven by, the one who comes to my simchas, ect.
To call a “community rov” like Rabbi Goldwasser? Unless directed to do so by my primary rov, that call should wait till a reasonable time. And if you don’t have a primary rov, the middle of the night/ crisis time is not the time to start a relationship
