Research direction
Start by tracing SessionPool.Reconnect and ExecuteClientOperationAsync, then inspect ConcurrentClientQueue.Take() using the reported InsertAsync path. Reproduce a DDNS address change during a connection and verify that the session pool can reconnect and recover instead of remaining empty or timing out.
Written by the indexing model from the issue text.

因为使用的DDNS，中途出现IP变化网络波动后就再也连不上了，有概率出现
