Failed to load data sources

Getting the following error. I tried to publish as another name and not a single issue. I cannot delete the data set and remake it again, this would be the 5th time and takes over a days work to recreate all 40 dashboards everytime. 

This happens when i try to go into the schedule refresh. Also get a timeout error when trying to get gateway informaiton.
