ssrs how to make the report available to my local machine
Firstly, the URLs referenced in the screenshots aren't the same: http://server/Reports_GP vs http://server/reportserver. In the comments, you clarified that you've double-checked on URLs, and confirmed that it still isn't working.  On to the next step!

The error indicates that your browser session isn't connecting to the service itself--however, since you're able to run the browser on the server itself and connect successfully, we know the service is listening. If you check the SSRS logs (Depending on your instance root directory, they will be somewhere like: C:\Program Files\Microsoft SQL Server\MSRS13.MSSQLSERVER\Reporting Services\LogFiles), you should be able to confirm that the SSRS service isn't receiving any connection. 

This indicates it is likely a networking / firewall / connectivity issue of some type. Is HTTP traffic being allowed through all firewalls (physical &amp; software) between your desktop &amp; the server? Most likely this issue is not a problem with SSRS, but rather a problem reaching SSRS.
