ARIS Design Server error

Hi All,

I am facing an issue in which when I try to run a query over anything( models, objects or groups) it displays an error message saying "ARIS design server is not available" .

This message is also shown when I directly go to Query--> Private/Public  in Analysis. Also I cant see any query there.

Has anyone please Guide me in this case as I am not able to run any query.

Thanks
