Develop Once, Deploy Anywhere!

Hello.
I use CrossUI RAD Studio for Linux. Pressing the "Debug Application" on the toolbar, and then, in the window that opens press the button "Show Debug Window" get the error: "... The requested URL could not be retrieved. When a URL http://127.0.0.1:39471/devtools/devtools.html? The following error occurred. The connection to 127.0.0.1 failed ..... ". I think the port starts debugging (in this case 39471) must be open (iptables). But it is changing with each launch. How do I open it? Maybe somewhere in the settings, you can define a constant to the port?
Thanks.

The port is created by NW JS, automatically.

How, run the debugger under Debian, in fact created by port NW JS automatically, but Debian port that is closed?

Please check your permissions issue

Also check your log file, to see why the port is not open

The full error message is as follows:
-------------------------------------------------------------------------------------------------------------------------------------------------------------
ERROR
The requested URL could not be retrieved
Upon receiving the URL http://127.0.0.1:58728/devtools/devtools.html? the following error occurred
Connection to 127.0.0.1 failed
The system returned: (111) Connection refused
Remote host or network is unavailable. Retry the request later

As root it works normally. But working as root is not correct. I can assign user rights to a resource debugging, but I do not know where he is. You can tell me?
