How to fix “The CORS protocol does not allow specifying a wildcard (any) origin and credentials at the same time” error

Question

I\'ve already enabled CORS on the project in C# .net Core

In startup.cs I\'ve added lines

...
app.UseCors(builder =

I had the same issue, the problem was solved by removing slash( / ) from the ending of URL, because I always copy and paste urls from chrome browser and it has the / at the end :

  .WithOrigins("https://localhost:60576/")  // not working 

but

  .WithOrigins("https://localhost:60576")  // working  !!!
