Won't switch to polling transport when Websocket transport failed about socket.io-client HOT 3 OPEN

Hi!

The order in the transports option matters:

const socket = io("https://example.com", {
  transports: ["websocket", "polling"] // use WebSocket first, if available
});

socket.on("connect_error", () => {
  // revert to classic upgrade
  socket.io.opts.transports = ["polling", "websocket"];
});

Reference: https://socket.io/docs/v4/client-options/#transports

from socket.io-client.

@darrachequesne okay, so if Websocket is blocked by proxy and unable to connect, shouldn't it switch to polling?

Anything? What's the point of having multiple transports if automatic switching doesn't work?
