64.86.136.45 isn't responding. Probably one of:

1) You don't have a route to it.

2) You need ebgp-multihop but haven't configured it. (If it's not on a
directly connected network or you're using update-source loopback, you need
ebgp-multihop)

3) (Unlikely, I suspect you'd get a different error) It's not configured to
talk BGP to you.

Is this host reachable for you?
Is this host directly connected to your router or this host is multihop?

Another (related) possibilities:

the other router doesn't have a route back to your router's configured
BGP address (or it doesn't have multihop configured, etc.)
