The readme example/instructions need to be updated. We do host a rendezvous server for demos and experimenting at /dns4/ws-star.discovery.libp2p.io/tcp/443/wss/p2p-websocket-star. This shouldn't be used for production.

The ws-star-signal-1.servep2p.com address actually points to 127.0.0.1, which requires you to run your own rendezvous server locally. Directions for installing and running rendezvous locally are at https://github.com/libp2p/js-libp2p-websocket-star-rendezvous#usage.

Running a rendezvous server, rendezvous --port=9090 --host=127.0.0.1, will give you access to a swarm address of /dns/ws-star-signal-1.servep2p.com/tcp/9090/ws/p2p-websocket-star/.

@jacobheun Note that ws-star-signal-1.servep2p.com was my self-hosted instance which I took down a few months ago because protocol labs is now hosting one. I only kept the subdomain to avoid people grabbing it

[jacobheun]

@mkg20001 ah, that's good to know, thanks! We should make sure to switch the host on examples using local rendezvous servers so we're not referencing that anymore. The rendezvous repo will also need to get updated with this.

I'm having trouble using js-ipfs in the browser to connect to a remote rendezvous server.

Firstly, setting up IPFS like this:

this._ipfs = new Ipfs({                                                      
  EXPERIMENTAL: {                                                            
    pubsub: true                                                             
  },                                                         
  config: {                                                            
    Bootstrap: [                                                             
      "/dns4/ws-star.discovery.libp2p.io/tcp/443/wss/p2p-websocket-star/",   
    ]
  }
});

throws an error: [1] "0" must be in IPFS format�

Then, even if I just write a simple WebSocket test script:

websocket = new WebSocket("wss://ws-star.discovery.libp2p.io:443");

It tells me WebSocket connection to 'wss://ws-star.discovery.libp2p.io/' failed: Error during WebSocket handshake: Unexpected response code: 502

[jacobheun]

@aphelionz the error you're hitting is due to the Bootstrap address not being an ipfs address (default addresses for bootstrap are here). Anything in config.Bootstrap is going to get dialed to, and it expects that to be an ipfs node. The discovery server should be used in the swarm addresses field

config: {
    Addresses: {
      Swarm: [
        '/dns4/ws-star.discovery.libp2p.io/tcp/443/wss/p2p-websocket-star/'
      ]
    }
  }

which will have the ipfs node listen to connections from that server.

[aphelionz]

@jacobheun thanks for the clarification. Is there anything I can do on the server side so that it's not refusing connections?

[jacobheun]

@aphelionz are you getting errors with the updated configuration? Or are you trying to hit it directly with WebSocket script you referenced above?

If you're using the script, I'm not sure which library you're using or what the rest of the script looks like, but libp2p-websocket-star does some processing of the address so the final dial actually looks like https://ws-star.discovery.libp2p.io if it has been given the discovery services multiaddress.

[aphelionz]

Thank you. So now I have:

this._ipfs = new Ipfs({
  EXPERIMENTAL: {
    pubsub: true,
    relay: {
      enabled: true
    }
  },
  config: {
    Bootstrap: [
      "/dns4/us-east-2a.ipfs.tallylab.com/tcp/4003/wss/ipfs/QmUjqjKVmWiXJp9HxBJ...'
    ],
    Addresses: {
      Swarm: [
        '/dns4/ws-star.discovery.libp2p.io/tcp/443/wss/p2p-websocket-star/'
      ]
    }
  }
});

That gives me this error in Chrome on Ubuntu:
