Invaild URL: Invaild port specified-CodePudding

I am trying to run the project using IIS Express and i get this error message Invaild URL: Invaild port specified

I tryed to change the port but it does not work

CodePudding user response：

Please,send your Properties/launchSettings.json. Probably you must add https:// to your url.

CodePudding user response：

According to the error message, it seems you used the invalid port url inside your launchsetting.json file.

I suggest you could firstly check its IIS express settings to make sure it looks like below:

  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:45519",
      "sslPort": 44315
    }
  }

Besides, the IIS express's SSL port range contains specific limit, the range must inside the 44300 through 44399 for SSL.

More details, you could refer to this article to understand how it works .
