Server Error 1370

Hi, I got an error like this. The ERPNext already installed and running. When I open CRM Dashboard, the charts are showing but ‘Loading’ and there is a pop-up message like this one.

pymysql.err.OperationalError: (1370, "execute command denied to user '<server name>'@'localhost' for routine ''")

Anyone know about this? And is there any solution to this kind of error?
Thank you

I am having the same problem with CRM as well. Anybody able to help us?
