Today I start my b4i project.
When I use my project with Hosted Builder, all steps are well done and app is installed on my iPhone.

When I use with my local macbook, it gave error as follow:

B4i Version: 5.51
Parsing code. (0.00s)
Building folders structure. (0.02s)
Compiling code. (0.01s)
Compiling layouts code. (0.00s)
Compiling debugger engine code. (0.73s)
Building Xcode project (0.23s)
Sending data to remote compiler. Error
Communication error: SendFailure

I also changed Userid for local. I also clean project. I tried again.
But error is same.

in macOS

b4ibuildserver is 5.50
I used server ip
port 51041

My macOS version is 10.14.3
XCode version is 10.0
iPhone version is 12.1

How can I fix it.
