I used Window 10 wallet
But i can not sync because No block soure?
Please help me or share me node to sync my wallet
I don't know about Windows 10, I used Win 8.1 and had that message once or twice. After a few minutes, it started syncing again. My wallet is now fully synced.
You can try exiting and then re-opening the wallet a few minutes later, maybe that will help.
