When I open SharePoint Central admin and Application Portal
got the following Message “Cannot
connect to the configuration database”
I checked and confirmed the below are looks good as per Microsoft
link
but the issue is exist.
- SQL Services are up and Running
- The SharePoint and SQL Server are talking together
- Nothing Database in Suspect Mode
- No Port Blocking in Firewall
- SharePoint Account had proper Permission in SQL
Finally found that the Application Pool account was locked
due to some reason which caused the “Cannot connect to the configuration
database” issue.
The Central admin and Application Portals are working fine
after the Application Pool account unlocked for my incident.
