I found my Apple TV show this message connect VPN, change Wifi (My VPN is local server proxy,not one connection VPN) then show always show connected,disconneted notification message.

In my case, I use. webview.evaluateJavaScript("") method can not use other third party javascript like jquery,angular so i use window.postMessage('','') like this webview.evaluateJavaScript("window.postMessage('param', '*')") and in html file, window.addEventListener("message", function(event) {     fn_start(event.data)   }); to solve this problem. hope help other people.
