This seems like a temporary warning. Did your Zero process get killed? From your logs, it looks like Zero has started fine. Can you try hitting the http://localhost:6080/state endpoint?

Here is what I got :

{
    "counter":"4",
    "zero":{"1":{"id":"1", "addr":"localhost:5080", "leader": true}},
    "cid":"a6bd230d-3f3f-461d-9da8-f6f47d2e7ec6",
    "license":{"maxNodes":"18446744073709551615", "expiryTs": "1590471474", "enabled": true}
}

Looks like its working fine then.

Just as you said, its working fine now!
I guess the Read index content time out is not a big problem
Thanks for helping me！
