I tried to test the web socket with the MS Edge (chromium) Version 83.0.478.58 and Google Chrome Version 83.0.4103.116
In my test, both the Chromium browser works well without 1006 error.
Here is the test code:
<!DOCTYPE html>
<meta charset="utf-8" />
<title>WebSocket Test</title>
<script language="javascript" type="text/javascript">
var wsUri = "wss://echo.websocket.org/";
var output;
function init()
{
output = document.getElementById("output");
testWebSocket();
}
function testWebSocket()
{
websocket = new WebSocket(wsUri);
websocket.onopen = function(evt) { onOpen(evt) };
websocket.onclose = function(evt) { onClose(evt) };
websocket.onmessage = function(evt) { onMessage(evt) };
websocket.onerror = function(evt) { onError(evt) };
}
function onOpen(evt)
{
writeToScreen("CONNECTED");
doSend("WebSocket rocks");
}
function onClose(evt)
{
writeToScreen("DISCONNECTED");
}
function onMessage(evt)
{
writeToScreen('<span style="color: blue;">RESPONSE: ' + evt.data+'</span>');
websocket.close();
}
function onError(evt)
{
writeToScreen('<span style="color: red;">ERROR:</span> ' + evt.data);
}
function doSend(message)
{
writeToScreen("SENT: " + message);
websocket.send(message);
}
function writeToScreen(message)
{
var pre = document.createElement("p");
pre.style.wordWrap = "break-word";
pre.innerHTML = message;
output.appendChild(pre);
}
window.addEventListener("load", init, false);
</script>
<body>
<h2>WebSocket Test</h2>
<div id="output"></div>
</body>
</html>
Reference:
Web socket echo test
Try to check the security settings of the browsers and also confirm that you are trying to connect using a secure connection.
I found that 1006 is a special code that means the connection was closed abnormally (locally) by the browser implementation.
I suggest you can check WebSocket.onerror(evt) to get more details about the error.

If there is more information then you can try to provide us that may help to narrow down the issue.
