Incorrect wallet's ballance -REWARD

I have unusual problem with balance on my wallet.
I downloaded the wallet, then i created wallet’s address and sent my coins on them. But my wallet wasn’t fully synchronized.
I checked status of my transaction using blockexplorer. Coin are on the typed address but ballance of my wallet is still 0 .
Is there hope of getting back the coins on my wallet ?

Easy, you should try to rescan the blockchain if you are on mobile wallet there is the option to rescan blockchain on the settings. If you are on the desktop wallet then you can try the command rescan.
Hope this helps.

“Method not found (code-32601)”

is the wallet fully sync now?

yes , it;s fully synchronized now

now do the rescan
