Peer Re-connection problem

[Ariful Islam]

Hi,

We're using jDimaeter for Ro Direct Debiting purpose. Recently we faced a strange problem - sometimes we have fluctuations in the network connectivity and Diameter server becomes unavailable and peer connection is lost. But even after the connectivity is restores, our Stack is not reconnecting automatically. Can anyone please suggest what I'm doing wrong here?

Below is my diameter configuration:
