There has been a planned fork on the Dash network, and all clients working on v17 might get stuck at the above block.
To resume syncing with the blockchain, download the newest version of the wallet from dash.org/downloads, go to the console and execute these commands one after another:
invalidateblock 0000000000000001342be9c0b75ad40c276beaad91616423c4d9cb101b3db438
mnsync reset
clearbanned
reconsiderblock 0000000000000001342be9c0b75ad40c276beaad91616423c4d9cb101b3db438
If the above solution does not help go through the below solution.
In order to solve the issue simply start Dash Core wallet with the -reindex command line parameter to initiate a reindex. Alternatively, you can add reindex=1 to the dash.conf file before starting Dash Core but it's very important to remember to remove that line from the file before the next time you restart or it will start the lengthy process of syncing all over again."In order to solve the issue simply start Dash Core wallet with the -reindex command line parameter to initiate a reindex.
