Problem with execute_file_in_blender.py

[guestieng]

Hello,
in the the basic usage description two ways are described how one can send python code to blender.
The first one works without errors.
The second way via the execute_file_in_blender.py, however, is not working (Blender 2.81a).
In particular, connection errors appear.
To this end I used the command
$ python <directory>/execute_file_in_blender.py "<directory>/test.py" 5000
with test.py containing simple code like print("test").
However, the same problems happen when using PyCharm as suggested.
