Websocket listen no longer works

[sschueller]

Using the example code from the documentation (https://developer.bitcoin.com/slp/docs/js/socket). I no longer get mempool entries. If I do the same query at https://slpsocket.bitcoin.com/channel I get entries. Making a query for "transactions" works fine.

Using version: 4.15.0

yarn init
yarn add slp-sdk

let SLPSDK = require('slp-sdk');
let SLP = new SLPSDK();

let socket = new SLP.Socket({
    callback: () => {
        console.log("connected")
    },
    wsURL: "wss://ws.bitcoin.com"
});
socket.listen(
    {
        v: 3,
        q: { find: {} }
    },
    msg => {
        console.log(msg)
    }
);

Any ideas?

Bitbox sdk works fine:

yarn init
yarn add bitbox-sdk 

let BITBOX = require('bitbox-sdk').BITBOX;
let bitbox = new BITBOX();

let socket = new bitbox.Socket({
    callback: () => {
      console.log("connected")
    },
    wsURL: "wss://ws.bitcoin.com"
  })
  socket.listen(
    {
      v: 3,
      q: { find: {} }
    },
    msg => {
        console.log(msg)
    }
  )
