Error 503 installing UnityDownloadAssistant-5.4.3xEditorVR-p3.exe

The EXE opens ok but when it try to download the Edito, show error 503 and i can't continue.

Any idea?

PS: I've downloaded this EXE from here (https://forum.unity3d.com/threads/welcome-to-the-editorvr-forums.446379/) to use the new EditorVR. I don't know other download link

 

It's fixed today. Perhaps one unity server was down this weekend
