Report Server has encountered a SharePoint error.

Question

Hi,
I am getting following error when i try to browse the reporting service url.
http://servername/ReportServer
Report Server has encountered a SharePoint error. The system cannot find the path specified. (Exception from HRESULT: 0x80070003)
It is configured in sharepoint integrated mode.
Created a site collection with "Business Intelligence Center" and published couple of reports and it gets renderd. Everything seems to be working except for browsing the reporting service URL.  Here is the Log info.

Detach the contentdb from SP and then reattach it. To do that you'd run this command:
STSADM -o deletecontentdb -url https://******.com -databasename whateverdb
Then to add it back you'd do:
STSADM -o addcontentdb url https://******.com -databasename whateverdb
Thank you Mike Yin, I have confirmed that this solution works, I had the exact issue, my investigation steps are in this order:
1. Verify if there is a orphaned site  (use stsadm.exe -o enumsites or stsadm -o enumallwebs or Test-SPContentDatabase
2. On my case I found the site orphaned on the root url [/] so I cannot just do a stsadm -o deletesite -force -siteid, so I did is to Remove Content from the CA and then re-add the content db back using CA. (Application Management > open the affected
Content DB and click the Remove content database checkbox. Then click Add a content Database, and re-add the same contentDB.
3. Verify in the RS Config Manager and click the RS Web Service URL, to see if works.
