Hello. In April, the wallet stopped synchronizing. I registered the nodes but did not help. I did not understand then. Now I tried again. Wallet is not syncing. I launched the wallet on another computer, there it synchronized, replaced walet.dat with the old one, but the coins did not appear, I see only the history of balance 0. By Blockchain Explorer I see that the coins are on the wallet. What needs to be done to keep the balance updated? Wallet latest version.
