That's a natural first impression but there are no passwords configured on the BGP session on either router. I know it looks like an authentication error but it's a "misnomer" (at least from the searches I did on the error message). From the sequence of messages, we get Established and 2 seconds later the session Closes. The reason for the Close may lead us to the solution.
I'm reluctant to turn on debug bgp because this is a live production router, and if I hose it, there will be a lot of 'splainin to do
