After these errors have stopped, see this thread: QKC Cluster errors stops cluster instance on docker the QKC cluster is running now without any errors. All the mining clients are running fine but somehow no QKC rewards are coming in on the wallet address used in the cluster? Last was 12 hours ago. This is very strange!
Have you ever received rewards before? It’s strange that you can’t receive the rewards unless the node didn’t finish syncing.
Please try stats tools to find out if it finished syncing.
