When i click on Content Sources on my Central Administration in SharePoint 2013. I get the below error
Cannot open database "Search_Service_Application_1_DB_2fxxxxx" requested by the login. The login failed. Login failed for user 'xxx'.
When I went to database server and when i click on + sign of respective database it was not opening. Why is this happening ?? My Search on site works fine but not able to open most of the search administration pages on central Administration.
