Is there a solution with blocks that have 1 confirmation? Solo mining
No, i also have some per day, restart wallet it will disappear but balance still deducted. 
I think it is orphan blocks. Someone else finds the block at the same time as you and it is confirmed by their miner slightly faster than yours causing the block you found be orphaned.
Thank for the clarification Envist This is a common issue with solo mining. If someone is mining at a higher hashrate and confirms it just before you did it will end up going to them instead of you.
