How do you run your application and what OS you use ? – Eugene Jul 10 '20 at 21:44

Try disabling SSL (switch to http). I think that's where your problem is. If the web traffic isn't leaving the computer, it doesn't really introduce a huge security threat. – itsme86 Jul 10 '20 at 21:45

Is port 57830 HTTP or HTTPS? – itsme86 Jul 10 '20 at 22:38

Does this answer your question? [C# Web - localhost:port works, 127.0.0.1:port doesn't work](https://stackoverflow.com/questions/23403912/c-sharp-web-localhostport-works-127-0-0-1port-doesnt-work) – Eugene Jul 15 '20 at 23:56

As a workaround you can map 127.0.0.1 to localhost manually. To do so, go to hosts file(location should be something like c:\Windows\System32\Drivers\etc\hosts) and add following line and save the file:
127.0.0.1 localhost
