I'm solo mining on windows and gubic isn't keeping up with current block. I'm consistently connected to three peers, but mining on old blocks. I had this issue several years ago with geth and was able to correct it by specifying more peer nodes in the .conf file.
I can't seem to find a peer node list to try this. I'm not sure this is even the problem. I'm running current release of gubic and rc3 of ethminer. Has anyone experienced this? Any advice greatly appreciated.
