my wallet the same,out of sync,but my wallet have 5 active connection.why?
As we know,the wallet did not has any sync problem. Maybe sometime is just during the stake generate time,hence many transactions just come in the same time,hence wallet will appear to out of sync problem,but don't worry,it will fix itself just a little time
