问题：在建立SharePoint List的报表时，出现基础连接已经关闭: 未能为SSL/TLS 安全Underlying connection was closed – could not establish trust relationship for SSL/TLS
So here is the next issue with SQL Server 2008 Reporting Services. “The underlying connection was closed: could not establish trust relationship for the SSL/TLS secure channel.”
This error popped up after a fresh, successful installation, when I tried to access the report manager at http://localhost/Reports_SQL2K8
Well, this one was not so difficult to figure out. Since the error clearly said that it has something to do with SSL. I fired up Reporting Services Configuration Manager. And clicked on “Report Manager URL” section, and this is what I saw:
If you observe, https:// has been configured. But I did not do it. May be, the default configuration. I clicked on Advanced. See the screenshot below:
If you observe, default SSL certificate for both IPv4 & IPv6 was configured which was causing the problem. This default configuration was done by SSRS 2008 installation. I suspect, this was due to Windows Server 2008 R2 network services or any other role/feature I enabled before SSRS installation. Now, I did not need SSL configuration on my personal laptop and/or this configuration had to be fixed. I removed both the configurations and clicked OK. But it still not done. The same configuration has to be removed from “Web Service URL” section in SSRS configuration – exactly in the same way.
That’s it. You are done. The Report Manager was now showing up, successfully.
