chat-with-rendezvous does not work about go-libp2p-examples

I just had the same issue. Seems like discovery.Advertise() failed.
Changing the RendezvousString also does not help.

Had the same issue. Additionally, my output says "dht: Bad dht record"

Most of them are WARNINGS and you should not worry about them.

Warning like 12:19:50.728 WARNI dht: error bootstrapping: failed to find any peer in table dht_bootstrap.go:86 is generated because of random walk algorithm which generates random peer ID's and try to connect to them even before we are connected to any node and hence no peer is available in the routing table.

Warnings like

12:19:50.768 WARNI rendezvous: dial attempt failed: no good addresses chat.go:139

I guess because of DNS multiaddr bootstrap nodes like /dnsaddr/bootstrap.libp2p.io/ipfs/QmNnooDu7bfjPFoTZYxMNLWUQJyrVwtbZg5gBMjTezGAJN which are not yet supported by the swarm. @Stebalien might be able tell you more about this.

Example should work regardless of the warnings generated. (Tried)

I think it would be good not to display too many logs to someone who is new.
