Wish I could help! My wallet isn't used for mining and I cannot get it to sync. At first it would not connect to the blockchain. Then I got it to a point where it would start reindexing blocks on disk for about 5 minutes then all the sudden no block source available. I had a lot of people help but nobody seems to know what the issue is. I tried messaging Giskard about it quite a few days back but no response. Good luck!
