chat with mdns does not work on the internet about go-libp2p-examples

@bnsh12 any tip from you would be appreciated.

AFAIK we cannot use multicast in public internet. You might have to use DHT to find nodes in this scenario.

You can try private networking options like VPC to create a subnet in cloud, but I am not sure multicast will work there either.

Thanks for the info. I'm now using DHT to discover peers but that too is not working in the AWS public internet as the private IPs are the one being sent in MultiAddr[]

I think the only option is to create a VPC and do this

DHT should work. Which example are you using and what is your setup?

[jeshocarmel]

I have a simple-bootstrap-node and two instances on AWS which are not connected locally. These two instances are able to connect to the bootstrap server individually but are not able to discover each other

@jeshocarmel can you try this example and use peer argument to pass the multiaddr of your bootstrap node.
