Dashboard can not load after server reboot

We are using jaspersoft embeeded BI from (AWS MarketPlace). Yesterday, we did development a dashboard using AD HOC feature, the dashboard was working and in the last of the day, we turn off the instance in AWS console normally. Today in the beginning of the morning, we turned on the instance, but when we try load the same dashboard that we created (yesterday), we can not do it. Anyone example can not be loaded too. Attach are some examples. NOTE: the datasource is OK and the dataset too. Can you help me? Leandro Ferreira
