After debugging my web api in Visual Studio 2019, I can visit it via localhost:11112. I would like to visit my website on a different computer from which it is being served upon that is also on the same network. To do this I should be able to visit that computers address which is 192.168.1.129:11112.

However when visiting this address I get a 'Bad request, invalid host name' error. Even if I visit it on the same machine as the website is being served on.

I already reference this answer but it not work too

did you try localhost:11112? if you did, you have add some specification for the url in configuration file – Fatih TAN Feb 18 '21 at 07:13
@FatihTAN localhost:11112 is working like the picture above, and I try config in applycationhost.config , but it is still not working : – Phuong Pham Van Feb 18 '21 at 07:36
I recommend that: true and in PropertyGroup node. Also in --> --> --> add/modify True, True, http://127.0.0.1:11112/, 0 – Fatih TAN Feb 18 '21 at 07:53

@PhuongPhamVan can you please check your appsettings.json? if that has not "AllowedHosts": "*" your appsettings.json should look like this https://pastebin.com/ADxnXpfE – Syed Mohammad Fahim Abrar Feb 18 '21 at 08:39
