Hello @Mohammad Qasim ,
Please perform the following troubleshooting:
1.Check whether the "SharePoint Central Administration v4" Application Pool is started
2.Check whether the Central Administration service is in disabled state:
$CA = Get-SPServiceInstance | Where-Object {$_.TypeName -eq `Central Administration'}
write-host $CA.status
If returns "Disabled" as Central Administration Service Status. Lets start the service:
Get-SPServiceInstance | Where-Object {$_.TypeName –eq ‘Central Administration’} | Start-SPServiceInstance -Confirm
Wait till it comes to "Online" Status.
write-host $CA.status
3.If you still cannot display the page, please check ULS logs and Event logs to get detailed error message
Thanks,
Echo Du
