I have added paste the nodes into vsync.conf. It's been hours and still out of sync.
restart the wallet after adding the nodes.
if it still can not be solve. Backing up wallet, delete all things in the Vsync folder, except vsync.conf file and masternode.conf file (if you are masternode owner), then reinstall Vsync wallet, replacing wallet.dat with your back up file. Then let the new installed wallet a few minutes to sync with network. Everything will be fine for your wallet.
Let do it and enjoy syncing results.
