Gin Cors Middleware in go preflight request

Hi, I need your help. After hours searching how expose cors middleware I haven't found any about it (different to my config).

I expose some middlewares in my main.go file

//Start default router
r := gin.Default()

// Health route
r.Group("/").GET("/health", c.Health)

// Subpath
routes := r.Group("/v1")

// We get the config from consul
jwtParser := jwt.NewParser(consul.ConsulConfig.GetJwtParserConfig())

// CORS
routes.Use(auth.CORSMiddleware())

// Every route it will be analized by this middleware
routes.Use(auth.Middleware(jwtParser))

In the CORSMiddleware I have the following code:

   func CORSMiddleware() gin.HandlerFunc {
    return func(c *gin.Context) {

        c.Writer.Header().Set("Access-Control-Allow-Origin", "*")
        c.Writer.Header().Set("Access-Control-Allow-Credentials", "true")
        c.Writer.Header().Set("Access-Control-Allow-Headers", "Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization, accept, origin, Cache-Control, X-Requested-With")
        c.Writer.Header().Set("Access-Control-Allow-Methods", "POST, HEAD, PATCH, OPTIONS, GET, PUT")
        if c.Request.Method == "OPTIONS" {
            c.AbortWithStatus(204)
            return
        }
        c.Next()
    }
}

I am developing a website that I need to make some gets and posts to my dev go server, I send some requests from localhost:4200 and I get an error..

Access to XMLHttpRequest at 'https://xxxxxx/v1/xxxx/usage' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: Redirect is not allowed for a preflight request.
zone.js:3382 POST https://xxxxxx/v1/xxxx/usage net::ERR_FAILED

Is that line in the cors middleware not working? Or I missing some config to accept requests from any origin?

c.Writer.Header().Set("Access-Control-Allow-Origin", "*")

Thanks!
