Hello,
I’m building chat application using IPFS pubsub (with help of ipfs-pubsub-room)
[https://chat.poadapps.com](https://chat.poadapps.com)
and I have problems with setting up nodes
I’m getting error (You can see it in console log of website):
```
bundle.js:37906 WebSocket connection to 'wss://ws-star.discovery.libp2p.io/socket.io/?EIO=3&transport=websocket' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
WS.doOpen @ bundle.js:37906
.............
bundle.js:36738 Uncaught Error: websocket error
at WS.Transport.onError (bundle.js:36738)
at WebSocket.ws.onerror (bundle.js:37944)
```
I believe it is related to following code
```
const node = new IPFS({
repo: repoName,
EXPERIMENTAL: {
pubsub: true,
dht: false /*TODO jak załadować options.modules.dht*/ ,
sharding: false
},
config: {
Addresses: {
Swarm: [
'/dns4/ws-star.discovery.libp2p.io/tcp/443/wss/p2p-websocket-star'
]
}
}
});
```
I’ve tried to change Address to:
“/dns4/star-signal.cloud.ipfs.team/wss/p2p-webrtc-star”
but it does not solve the problem.
If I do not specify adresses nodes do not see each other
Also I could swear several days ago this code worked 😅

The signal server is down. You need to run your own.
Just install it with npm and it gives you a global command star-signal

> libp2p WebRTC transport that includes a discovery mechanism provided by the signalling-star - libp2p/js-libp2p-webrtc-star
Unfortunately there are no instructions on there on how to setup a secure wss signal server.

Hi,
thank You for answer
On github I can find:
A libp2p-webrtc-star address, using the signalling server we provide, looks like:
/dns4/star-signal.cloud.ipfs.team/wss/p2p-webrtc-star/ipfs/\
How i can get my \
without initializing Ipfs object (I need this address on initialisation phase)
Also,
**How to make such website trully decentralized? If my web still requires to connect to specific server I run, whole thing goes down if discovery goes down**
**can list of all available discovery servers be fetched from somewhere**?
For example current IPFS hash of nodes list stored on Ethereum blockchain 😃
I’m still learning and it is all a kind of magic.

Hi,
you need to run your own app’s signal server along with your web app.

@gyuri
thanks for help,
however I’m facing new issue now:
It does not throw error after bootstraping in following way:
```
const node = new IPFS({
repo: repoName,
EXPERIMENTAL: {
pubsub: true,
dht: false /*TODO jak załadować options.modules.dht*/ ,
sharding: false
},
config: {
Addresses: {
Swarm: [
"/dns4/ec2-3-86-86-35.compute-1.amazonaws.com/tcp/9090/ws/p2p-websocket-star/ipfs/" + from.id,
]
}
}
```
});
But now
node.swarm.peers().then(console.log)
is empty
and
node.bootstrap.list().then(console.log)
returns one element
["/dns4/3.86.86.35/wss/p2p-webrtc-star/ipfs/QmYiXvGjRAsviVo5g56evAbSVpvJQG9kEmqLZu4d5Zx4di"]
Is theree something wrong with signalling-server ? Firewall?
My signalling-server is running
[http://ec2-3-86-86-35.compute-1.amazonaws.com:9090/](http://ec2-3-86-86-35.compute-1.amazonaws.com:9090/)
