Try to send your http header with username and password as Basic Authentication method
I tried this method on Jquery ajax call
var settings = {
      "async": true,
      "crossDomain": true,
      "url": "https://immense-depths-6983.herokuapp.com/search?search=94305",
      "method": "GET",
      "headers": {
        "authorization": "Basic YWRtaW46cGFzc3dvcmQ=",
        "cache-control": "no-cache",
        "postman-token": "54733c33-4918-811b-3987-69d6edeaa3a0"
      }
    }

$.ajax(settings).done(function (response) {
  console.log(response);
});

If after login it is working, means it is Authentication issue, so check authentication settings

it is very simple
Go to Startup.cs file and add the below code in Configure method, which will inject CORS into a container.
app.UseCors(options => options.AllowAnyOrigin()
.AllowAnyHeader()
.SetIsOriginAllowed(origin => true) // allow any origin
.AllowCredentials()
);
Add the below code in ConfigureServices method,
services.AddCors(c =>
{
c.AddPolicy("AllowOrigin", options => options.AllowAnyOrigin()
.AllowAnyHeader()
.SetIsOriginAllowed(origin => true) // allow any origin
.AllowCredentials()
);
});

Sachin Singh4y ago
Add this to your services
app.UseCors(x => x
                .AllowAnyMethod()
                .AllowAnyHeader()
                .SetIsOriginAllowed(origin => true) // allow any origin
                .AllowCredentials()); // allow credentials

Your Authentication service is blocking it. Ask your TL about the settings in startup.cs servicess.AddAuthentication({ what settings are listed here?})
