Actually the problem is that the first instance didn't receive incoming call. 实际上，问题在于第一个实例没有收到传入呼叫。 I checked the video chat example from quickblox's github. 我检查了来自quickblox的github的视频聊天示例。 It works with my users/passwords, so I have a mistake in my code, but I really don't know where I should search it. 它可以与我的用户名/密码一起使用，因此我的代码有误，但是我真的不知道应该在哪里搜索。
As you can see both instances have the same problem: "Socket closed by remote peer". 如您所见，两个实例都有相同的问题：“套接字被远程对等体关闭”。 But this problem happens after call timeout, so it isn't a cause of main problem. 但是此问题在呼叫超时后发生，因此不是主要问题的原因。

Finally I've found the solution. 最后，我找到了解决方案。 The problem was in QBVideoChat object. 问题出在QBVideoChat对象中。 I thought that QBChat will send me the signal when another user calls me and then I'll create the QBVideoChat object and present it's view on screen. 我以为QBChat会在另一个用户打电话给我时向我发送信号，然后我将创建QBVideoChat对象并将其显示在屏幕上。
The sad truth is that QBChat don't send any video relations signals before I create QBVideoChat. 可悲的事实是，在创建QBVideoChat之前，QBChat不会发送任何视频关系信号。 So I have to create it at program's start in order to receive chatDidReceiveCallRequestFromUser signal. 所以我必须在程序开始时创建它，以便接收chatDidReceiveCallRequestFromUser信号。
