Syscoin Core 4.3.0 Sync Error

Hello! I can not sync masternode after upgrading to Syscoin Core 4.3.0.
My Syscoin Core syncs blocks to init headers count. After that syncing process are breaking and my blockchain are standing on old position.
It is crashing masternode work and it can not work with others network’s nodes.
I tried to reinstall / reindex Syscoin Core many times already.
Please take your attention on this problem.
