Hi. I have my own blockchain forked from bitcoin. Also i have a mining pool.
It was working fine until node server fell down.

When server was restarted, the problem with syncronization apear. Wallets cant sync with node and says: "Synchronizing with network" or "No block source found".
It seams that some block information was corrupted on server, because blockchain height in my wallet is 6138, but in server - 6014, when is MPOS database last block height is 6139.

I tried to replace blockchain information on server with my own, but useless.

Help please, how can i fix this issue?
