CORS error not working on PUT and DELETE on net 6 web api

I have a web api net 6 published on a web hosting service (interserver), everithing works ok on all api methods, except on PUT and DELETE.

I configured Cors on Program.cs

app.UseCors(options =>
{
    options.AllowAnyOrigin();
    options.AllowAnyMethod();
    options.AllowAnyHeader();
    options.AllowCredentials();
});

also I tried the recommended method of

var myAllowSpecificOrigins = "_myAllowSpecificOrigins";

options.AddPolicy(myAllowSpecificOrigins, policy =>
{
    //policy.AllowAnyOrigin();
    policy.WithOrigins("http://localhost:52039", "https://www.-----.com")
    .AllowAnyMethod()
    .AllowAnyHeader();
});


app.UseCors(myAllowSpecificOrigins);

and same result, all GETs and POSTs works fine, all PUT and DELETE get a CORS error and 403 error (forbidden).

I've tried everything combining this methods and adding to the controllers [EnableCors(...)]

Nothing works

Can someone help me?

I am new to net 6.

Thanks in advance
