If you're here after you click download on Goplay, just click on the Download Video button because the video URL is already placed into the placeholder automatically. Clicking on Download Video will process the URL and display servers where you can download.

The processed URL will display different servers result. Use Direct Server first, if it doesn't work, come back and use another server.

If you click on Direct Server, it generates direct download links automatically, just click the MP4 360p button and your download will start automatically.

If Download doesn't start and video starts playing, click the three dots by the bottom-right of the video, then click download from the menu.

That's all... If the Direct Server method doesn't work, use other servers.
