rendezvous server failed and secure websocket failed

[kvutien]

I'm doing this awesome web3-workshop. I solved the 'multicodec' issue thanks to @tijsmaas. I stumbled on more warnings.

It seems that this repository may benefit from an update for 2021. I volunteer to do improvements and make a PR if someone can help me go through the gotchas until the end. I have noted down what I learned as I progress.

Thanks.

I'm currently starting branch 2-playlists-component. The 2 more issues I have are:

• the swarm rendezvous server that is hard-coded in class App gives the error: "WebSocket connection to 'wss://ws-star.discovery.libp2p.io/socket.io/?EIO=3&transport=websocket' failed." I solved it by commenting out this server
• now I have 6 messages

I'll continue because it is possible that these messages are only warnings.
