iOS Question app can not install in iPhone and Cannot connect to local ip

Hello,

I build an App with B4i.

1. I run or build it with hosted builder and my iPhone device.
The app is successfully installed.

2. I run or build it with local mac and simulator.
The app is also successfully installed.

Now I want to run and build with my local mac and my iPhone device.
All compilation is success. But any app is not installed on my iPhone.
In my iPhone, it show "Cannot connect to 192.168.1.6".

I change new build-sever on my mac's new folder and also change user id. Restart mac and XCode and run build server run again.

But result is same.
Message on iPhone


at Windows 10 and MacBook




My b4i is 5.51
build server is 5.50 on mac

XCode is 10.0
macOS is 10.14.4


Now I test my b4i project run with local mac and simulator and when I run on my real iPhone, I have to use hosted builder.
I want to build with my local mac and run it on my iPhone.
How can I fix it?

I also test http://192.168.1.6:51041/test on iPhone Browser.
It shows:
B4i Build Server
Build server is running
Version 5.5.

(Edit)
I delete B4i Bridge from iPhone.
I scan QRCode 192.168.1.6:51041/myios03. Install App Page is shown. After click this buton, "Cannot connect to 192.168.1.6" message is shown again.
Now there is no B4i App in my iPhone.

Thanks.
