RemoteDebuggingPort remote-allow-origins

[Zer0bytte]

When trying to open remote debugging this issue happens cefsharp v112 (latest version) and .net 7

[n303ef]

Try this:

cefSettings.CefCommandLineArgs.Add("remote-allow-origins", "*");

In future please use Discussions to ask support related questions.

Additionally please no images of code, cannot copy and paste from an image.

As @n303ef has pointed out your code is incorrect. It should be:

settings.CefCommandLineArgs.Add("remote-allow-origins", "*");

For security reasons wherever possible only allow specific origin(s).

settings.CefCommandLineArgs.Add("remote-allow-origins", "http://localhost:9955");

[0416/184046.922:ERROR:devtools_http_handler.cc(766)] Rejected an incoming WebSocket connection from the http://localhost:9995 origin. Use the command line flag --remote-allow-origins=http://localhost:9995 to allow connections from this origin or --remote-allow-origins=* to allow all origins.

Chromium will make a suggestion on which origin to allow in the log file.

Thanks @amaitland @n303ef

I was looking into same issue or feature for same reason. I've tried with different flags

settings.CefCommandLineArgs.Add("remote-allow-origins", "*");

And

settings.CefCommandLineArgs.Add("remote-allow-origins", "http://localhost:9222");
// ...

And with all combinations incl this as well

settings.CefCommandLineArgs.Add("remote-debugging-port", "9222");
settings.CefCommandLineArgs.Add("remote-debugging-address", "0.0.0.0");
settings.CefCommandLineArgs.Add("disable-features", "BlockInsecurePrivateNetworkRequests");        
            

I still could not access it from any other machine but localhost and 127.0.0.1. Even if I set

settings.CefCommandLineArgs.Add("remote-debugging-address", "192.168.0.211");  // for example

It still would not let me to connect when accessing via browser http://192.168.0.211
Have anyone had success on accessing it from other PC on the same network and what options have you used?

• Sidenote:
  I took another approach by using Proxy and that worked half way through. Debugging is using ws (web sockets) and that was the issue as proxy I was using would not pass ws through.

CEF version I am using is: 101.0.150

Are you sure the command line args are supported in this version? It's 11 versions behind the version mentioned in this discussion.

Try testing with the current supported version.
