How can I handle net::ERR_INTERNET_DISCONNECTED error in Net Core

I'm playing a stream live radio mp3 media, but when the internet connection is disconnected, stream playing stops and never plays again even the internet connection is back.

I want to handle the connection and when the connection is disconnected, I need to show an alert with a message like 'your connection is disconnected, check and refresh the page' to the user.

How can I handle this with Javascript or C#?

Use the below snippet

  1. Use chrome developer tools to put a browser on offline/online

window.addEventListener("offline", (event) => {
  const online = document.getElementById("online");
  const offline = document.getElementById("offline");
  online.style.display = "none";
  offline.style.display = "block";
});

window.addEventListener("online", (event) => {
  const online = document.getElementById("online");
  const offline = document.getElementById("offline");
  online.style.display = "block";
  offline.style.display = "none";
  setInterval(async() => {
    online.style.display = "none";
  }, 10000);
});

You should check on javascript is server connected or not. then if client not connected with server, u can refresh the page.
