Use pubsub between browser node and daemon node (go-ipfs)

Version: js-ipfs: 0.34.4 and go-ipfs: 0.4.19
Platform: js-ipfs on Chrome v. 72.0.3626.121 and go-ipfs on 64-bit Windows 10

Type: Question

Description:

I'm having difficulty using pubsub between a browser node (using js-ipfs) and a go-ipfs node running on my machine.

Node A is created programatically and runs in the browser. This node will Publish the message.
Node B runs as daemon in local machine, started via CLI. This node will Subscribe to a topic.

First, I tried to setup a direct connection between the nodes, but I keep getting the same error:

Since this was not possible, I attempted to setup a p2p connection between Node A and B. I believe this was done correctly. The browser logs:

Swarm listening on /p2p-circuit/ip4/127.0.0.1/tcp/4001/ipfs/QmPMaDyK2ee95BpjnMyWYiVi46EcZFrY8AUmSzieNSLbEa/ipfs/QmcCnVBpYLvcRLbutwRMkzeJwHfjbFaq8y9JQ2sLcBAX1L

Despite having set up the p2p circuit, the node running on my machine does not receive the message published by the node running on the browser.

Steps to reproduce the error:

I start the daemon on the terminal using: ipfs daemon --enable-pubsub-experiment and subscribe to the topic using ipfs pubsub sub testing123

I instantiate the node on the browser using:

this.ipfsNode = new IPFS({
      EXPERIMENTAL: { pubsub: true },
      relay: { enabled: true, hop: { enabled: true } },
      config: {
        Addresses: {
          Swarm: [
            "/ip4/127.0.0.1/tcp/4001/ipfs/QmPMaDyK2ee95BpjnMyWYiVi46EcZFrY8AUmSzieNSLbEa",
            "/dns4/wrtc-star.discovery.libp2p.io/tcp/443/wss/p2p-webrtc-star"
          ]
        },
        libp2p: {
          modules: {
            transport: [wstar],
            peerDiscovery: [wstar.discovery]
          }
        }
      }
    });

I navigate to localhost:3000 and the console logs:

Swarm listening on /p2p-circuit/ip4/127.0.0.1/tcp/4001/ipfs/QmPMaDyK2ee95BpjnMyWYiVi46EcZFrY8AUmSzieNSLbEa/ipfs/QmcCnVBpYLvcRLbutwRMkzeJwHfjbFaq8y9JQ2sLcBAX1L

Then on the browser, we try to communicate with the daemon using

publishFileHash() {

    const topic = "testing123";
    const msg = Buffer.from(this.state.added_file_hash);
    console.log("msg is");
    console.log(this.state.added_file_hash);

    this.ipfsNode.pubsub.publish(topic, msg, err => {
      if (err) {
        return console.error(`failed to publish to ${topic}`, err);
      }
      console.log(`published to ${topic}`);
    });
  }

After this, browser console logs: published to testing123 but the daemon does not get the message. :cry:

Question

I would like to know if it is possible to get the Pubsub functionality working between these two types of nodes. If so, I was hoping someone could point me in the right configuration for both nodes. The current configuration for both nodes can be found here:

Thanks!
