Handle IPFS init error if ws-star.discovery.libp2p.io connection fails

Just saw a peer-pad init fail with an error when it couldn't connect to wss://ws-star.discovery.libp2p.io

creating IPFS
WebSocket connection to 'wss://ws-star.discovery.libp2p.io/socket.io/?EIO=3&transport=websocket' failed: WebSocket is closed before the connection is established.

We could try again, remove ws-star from the config and try again, or just alert the user. Ideally we'd try n times with some backoff, and eventually let the user know that there is a problem finding peers, but we're retrying.
