If you use parity 2.3.5 syncing your blockchain and you open a geth console with the synchronization as well, your geth console might show that everything is synced but you can and error with ancient block syncing.
Like the following error: "Block information is incomplete while ancient block sync is still in progress, before it's finished we cant`t determine the existence of item"
In this case check the following :
Like the following error: "Block information is incomplete while ancient block sync is still in progress, before it's finished we cant`t determine the existence of item"
In this case check the following :
curl --data '{"method":"parity_chainStatus","params":[],"id":401697,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST localhost:8545
if it shows that there is still and existing blockgap it means that an ancient block syncing is still in progress, so wait until it finishes. If the sync does not improve check if you did not coicidently start parity with the --no-ancient option.
