Reporting Services - HTTP Error 404. The requested resource is not found.

What if you suddenly experience this when you open the Reporting Services Portal?

HTTP Error 404. The requested resource is not found.

There can be many reasons for this error and you may find the exact reason by reading Windows Application Log, Report Server Service Trace Log (default location is C:\Program Files\Microsoft SQL Server\MSRS13.MSSQLSERVER\Reporting Services\LogFiles) or SQL Server Error Log. When I go through the trace, I found that it was related to HttpListner and permission.

What shall we do? It is always better to find the exact root-cause and fix it. But, if you need to do a quick fix, there is a simple way to try and see.

It is all about change the Virtual Directories of Reporting Services. You may not fix the issue with this method but can try and see;

1. Open the Reporting Services Configuration Manager.

2. Go to Web Service URL and change the name of the Virtual Directory. In my case, it was ReportServer and I change it as ReportServer1.

3. Do the same for Web Portal URL too.

4. Once this is done, you should be able to open the portal. As you see, nothing has happened to content of it, it shows all items it had.

If you need to set the same Virtual Directories you had, you can do the same again for renaming them.

** Note that, you need to keep regular back of your report database and all content of report server. If you cannot get your errors fix, only option is reinstalling and setting it up again.
