Connection Failed. Unable to connect to the specified.
When trying to open and build a new report in 2012 Report Builder 3.0. Error states can't connect or don't have permissions for https://reports/everysport.net/reportserver. When connecting to the SSRS reports server via a web service, a TLS security conflict between the MS Report Builder service located on the cloud-based server and the client's computer is created.
This is a Microsoft issue. The underlying issue appears to be the version of report builder we're using only supports an older, less secure connection to the reporting service. When a client tries to connect our servers, the Microsft service refuses the connection because it isn't secure. Until Microsoft releases a hotfix for this, the file below needs to be executed on a client computer to enable a secure connection to the reporting service.
The reason for this is that Reports Builder is built with a version of the .NET framework that didn't originally support TLS 1.2. Updates to the .NET framework have enabled TLS 1.2 but unless programmatically told to, an application won't use it. We obviously can't change the code that Reports Builder uses. That's a Microsoft product that we can't affect but there is a solution. Making a change to your computer registry will force the application to use TLS 1.2
You may have to download a zip file containing registry entries to correct the issue. If so, please contact email@example.com.
Note: Making changes to your registry.
