Pico and WiFi unable to create socket

Just to add that there is something iffy going on with sockets getting into an invalid state, and that looks like a bug in the ESP8266 interface library for Espruino.

However, I think that's likely caused by trying to run the 3 sockets concurrently.

If you try this:

function getPrices() {
  symbolCtr = symbolCtr+1;
  if (symbolCtr>=symbols.length) symbolCtr=0;
  let symbol = symbols[symbolCtr];
  let url = `${proxy}${api}${symbol}-${currency}`;
  console.log("Opening socket");
  h.get(url, function(res) {      
    let pricesRaw = "";
    res.on('data', function(d) { pricesRaw += d; });
    res.on('close', () => {
      console.log("Socket closed");
      prices[symbol] = JSON.parse(pricesRaw);
      showPrices();
    });
  }); 
}

every 10 seconds then I bet it'll be a lot more stable.
