Glide unable to load url images of this type

I have used Glide many, many times before, but currently I am having issues to display images with this type of url https://www.publicdomainpictures.net/pictures/10000/nahled/thinking-monkey-11282237747K8xB.jpg, I don't know why is impossible for me to load it. I even simplified my project to only display this image on MainActivity. When I check the Listener of glide it prompts this error

2021-02-19 21:39:43.438 31240-31240/com.y4kuzabanzai.testforvass E/MainActivity: onLoadFailed: com.bumptech.glide.load.engine.GlideException: Failed to load resource
    There was 1 root cause:
    com.bumptech.glide.load.HttpException(Failed to connect or obtain data, status code: 503)
     call GlideException#logRootCauses(String) for more detail   

The thing is that I have tried with other Urls and they work just fine. What can be wrong? Here my simple code

MainActivity.class

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        var imageView: ImageView = findViewById(R.id.homeImage)


        Glide.with(this)

            .load("https://www.publicdomainpictures.net/pictures/10000/nahled/thinking-monkey-11282237747K8xB.jpg")
            .listener(object : RequestListener<Drawable> {
            override fun onLoadFailed(e: GlideException?, model: Any?, target: Target<Drawable>?, isFirstResource: Boolean
            ): Boolean {
                Log.e(TAG, "onLoadFailed: ${e}")
                return false
            }

            override fun onResourceReady(resource: Drawable?, model: Any?, target: Target<Drawable>?, dataSource: DataSource?, isFirstResource: Boolean
            ): Boolean {
                return true
            }
        })
            .into(imageView)

    }

activity_main.layout

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

               android:id="@+id/homeImage"
               android:layout_width="418dp"
               android:layout_height="492dp"
               android:layout_marginStart="14dp"
               android:layout_marginBottom="109dp"
               app:layout_constraintBottom_toBottomOf="parent"
               app:layout_constraintStart_toStartOf="parent"
               tools:srcCompat="@tools:sample/avatars" /> </androidx.constraintlayout.widget.ConstraintLayout>

I finally fixed it!!!!! The thing is that you have to use a header in such cases where you have to add a User-Agent. Here how I fixed it, note that since I tried several things my code may have changed a bit, thanks Faramarz Afzali for the time. Here my code:

private val USER_AGENT = "Mozilla/5.0 (Linux; Android 11) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.181 Mobile Safari/537.36"

val glideUrl = GlideUrl(
            gnome.thumbnail,
            LazyHeaders.Builder().addHeader("User-Agent", USER_AGENT).build())

        val requestOptions = RequestOptions()
            .placeholder(R.drawable.ic_launcher_background)
            .error(R.drawable.ic_launcher_background)


        GlideApp.with(itemView.context)
            .applyDefaultRequestOptions(requestOptions)
            .load(glideUrl)
            .timeout(60000)
            .override(320, 480)
            .into(binding.gnomeImage)
