Throws when IPv6 literals are used as signaling server (possibly due to nodejs/wrtc)

/ip6/2a03:b0c0:2:d0::10ca:6001/tcp/443/wss/p2p-webrtc-star throws but /ip6/2a03:b0c0:2:d0::10ca:6001/wss/p2p-webrtc-star works.

FWIW - the "correct" way to format the address is wss://[2a03:b0c0:2:d0::10ca:6001]:443/socket.io/?EIO=3&transport=websocket with the brackets indicating the colons belong to the IPv6 address itself, not to indicate the port
