TCP Socket does not seem to work on Worker
Just a small update. I was able to open https://connect.fifo.workers.dev/gopher/wbgopher from clicking the link in this thread, and see the response text. However, when I refresh the link, the same issue happens.

The same example code on the TCP sockets page: 
import { connect } from 'cloudflare:sockets';

export default {
  async fetch(req: Request) {
    const gopherAddr = { hostname: "gopher.floodgap.com", port: 70 };
    const url = new URL(req.url);

    try {
      const socket = connect(gopherAddr);

      const writer = socket.writable.getWriter()
      const encoder = new TextEncoder();
      const encoded = encoder.encode(url.pathname + "\r\n");
      await writer.write(encoded);

      return new Response(socket.readable, { headers: { "Content-Type": "text/plain" } });
    } catch (error) {
      return new Response("Socket connection failed: " + error, { status: 500 });
    }
  }
};
import { connect } from 'cloudflare:sockets';

export default {
  async fetch(req: Request) {
    const gopherAddr = { hostname: "gopher.floodgap.com", port: 70 };
    const url = new URL(req.url);

    try {
      const socket = connect(gopherAddr);

      const writer = socket.writable.getWriter()
      const encoder = new TextEncoder();
      const encoded = encoder.encode(url.pathname + "\r\n");
      await writer.write(encoded);

      return new Response(socket.readable, { headers: { "Content-Type": "text/plain" } });
    } catch (error) {
      return new Response("Socket connection failed: " + error, { status: 500 });
    }
  }
};
