Expected Behavior

Blocks can be synchronized and broadcasted normally, and no timeout should occur.

Actual Behavior

I deployed a private chain locally. The two nodes have been synchronizing and broadcasting blocks normally. However, after a while, they suddenly disconnected due to a TIME_OUT. Here is the last interaction log.
