State sync not working on mainnet

[Sotatek-SinhVu]

Here is my config.toml:

# If this node is many blocks behind the tip of the chain, FastSync
# allows them to catchup quickly by downloading blocks in parallel
# and verifying their commits
fast_sync = true

# As state sync is an experimental feature, this switch can totally disable it on core network nodes (validator, witness)
state_sync_reactor = true

# If this node is many days behind the tip of the chain, StateSyncHeight
# allows them to catchup quickly by downloading app state (without historical blocks)
# in parallel and start syncing block afterwards
# <0 - turn off state sync
# =0 - sync from peer's latest height
# >0 - sync from that height
state_sync_height = 50000000

# Only take effect when HotSyncReactor is true.
# If true, will sync blocks use hot sync protocol
# If false, still use tendermint consensus protocol, but can still handle other peers sync request.
hot_sync = false

# The max wait time for subscribe a block.
# Only take effect when hot_sync is true
hot_sync_timeout = "3s"

# It will benefit fullnode and witness who do not need consensus by saving network and cpu resources.
# Recommend the node that is not validator to turn on.
hot_sync_reactor = false

But, when I checked node status, it told me that:

"sync_info": {
    "latest_block_hash": "1CE3F85C0C9E97BE34D8D2825CA662E0CAFAE0DBE314B05F5C4B66019A528640",
    "latest_app_hash": "C3220ED358B68E4AC2DBF652E6DA5F4B06FF12ABFB703C077425204C17C8EE71",
    "latest_block_height": "23485",
    "latest_block_time": "2019-04-18T08:34:44.57135746Z",
    "catching_up": true,
    "index_height": "23484"
},

So, how can I start my node from any block?

hello, @Sotatek-SinhVu

Please set state_sync_height = 0.

hello, @Sotatek-SinhVu

Please set state_sync_height = 0.

@huangsuyu oh yes, it is working now.
But, if I want to specify the starting block height, the current is 50,000,000. Is it possible?
Thank you.

I'm afraid it's not possible. you can only state-sync from heights with snapshots.

@huangsuyu yes, thank you so much.
I thought I had the answer to my question. So, I will close this issue.
Thank you.
