I want to create an IPFS relay v2 node using kubo (latest)

Help IPFS
1

I tried setting Swarm.RelayService.Enabled to true and added “/ip4/0.0.0.0/tcp/4002/ws”, “/ip6/::/tcp/4002/ws”, in Addresses.Swam.

I am trying to connect my js-ipfs (browser-based) to this node using this config

 config: {
....
                Addresses: {
                    API: '/ip4/127.0.0.1/tcp/0',
                    Swarm: ['/ip4/127.0.0.1/tcp/4002/ws/p2p/<PEER_ID>/p2p-circuit'],
                    
                    Gateway: '/ip4/0.0.0.0/tcp/0'
                },
....
}

But it’s not able to connect it shows this error Error: Transport (Circuit) could not listen on any available address
btw if I use the WebRTC-Star signaling server with the same configuration (in Swarm), it works.

What I am doing wrong?
