Hi!
Failed to load URL http://.........:4045 with error ERR_UNSAFE_PORT (-312).
MiniBrowser
Code: Select all
procedure CreateGlobalCEFApp;
begin
GlobalCEFApp := TCefApplication.Create;
GlobalCEFApp.cache := 'cache';
GlobalCEFApp.EnablePrintPreview := True;
GlobalCEFApp.EnableGPU := True;
GlobalCEFApp.LogFile := 'debug.log';
GlobalCEFApp.LogSeverity := LOGSEVERITY_INFO;
GlobalCEFApp.AddCustomCommandLine('--explicitly-allowed-ports=4045');
end;
Does not work, in a normal browser, if you specify through the shortcut works, what is wrong?

Try replacing this line :
Code: Select all
GlobalCEFApp.AddCustomCommandLine('--explicitly-allowed-ports=4045');
with this line :
Code: Select all
GlobalCEFApp.AddCustomCommandLine('--explicitly-allowed-ports', '4045');
Navigate to "chrome://version" to see all the switches and compare the switches between the application with AddCustomCommandLine and the application that has a command line switch in the shortcut.

While this is not necessary, but the question arises, how to resolve any port?
It is not very convenient to add each time, it is only necessary if there is a need for such a restriction yourself, but if it is not necessary, then it is not necessary.

Chromium added this feature for security reasons :

Apparently, you can specify several ports separated by commas when you use that switch :
