IIS site within virtual directory Swagger UI end point

Question

Swagger UI end point is not same as dev in staging ( excluding domain names)

IIS Configuration

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)

 app.UseSwagger(c=>
        {
            //Change the path of the end point , should also update UI middle ware for this change                
            c.RouteTemplate = "api-docs/{documentName}/swagger.json";                 
        });          

        app.UseSwaggerUI(c =>
        {  
            //Include virtual directory if site is configured so
            c.SwaggerEndpoint(Configuration["Appsettings:VirtualDirectory"]+"api-docs/v1/swagger.json", "Api v1");                
        });

 services.AddSwaggerGen(c =>
        {
 var xmlDocPath = Path.Combine(PlatformServices.Default.Application.ApplicationBasePath, "Api.xml");
            c.IncludeXmlComments(xmlDocPath);
            c.DescribeAllEnumsAsStrings();

with the above configuration

Development

 "AppSettings": {
"VirtualDirectory": "/"

}

Staging

 "AppSettings": {
"VirtualDirectory": "/Api/"

}

The end point for UI on the dev machine with staging ON

http://localhost:5001/api-docs/v1/swagger.json

but the same one on the staging server

http://xxxx:5002/swagger/Api/api-docs/v1/swagger.json

instead of ( what it should be)

http://xxxx:5002/Api/api-docs/v1/swagger.json

Unfortunately, None of them works for me.
I have tried all of them.

Working solution:

app.UseSwagger(c => {
    c.RouteTemplate = "swagger/{documentName}/swagger.json";
});

app.UseSwaggerUI(c => {
    c.SwaggerEndpoint("v1/swagger.json", "My API V1");
});
