my wallet still not sync how to solve it
Do Nothing, just dont close it. For 1st open the wallet, its need very long long time to sync even with hundreds of nodes
Indeed, if you have added some nodes definitely give the wallet some time before giving up. I let mine hang there for awhile and it did nothing then all of a sudden took off. I'd say if after 2 hours you don't make any progress then you know something is wrong.
