如何解决PowerBi 报告服务器PBIRS 2021 年 1 月说“无法连接到分析服务服务器”，即使我没有使用它
我们有 3 台服务器开发、测试和直播。每个服务器是：
- Win2012R2
- SQL2016 SP2-CU15-GDR 13.0.5865.1 和
- PBIRS：版本 1.10.7737.32652（2021 年 1 月）
我们有一份报告，它适用于开发和测试，但在 Live 中失败并显示以下错误：
An unexpected error occurred
An unexpected error occurred. Please try again later.
Please try again later or contact support. If you contact support,please provide these details.
We couldn't connect to the Analysis Services server. Make sure you've entered the connection string correctly.:
Request ID: cc3b3bf4-bedd-12ea-2de7-01a00766d42e
Time: Wed May 12 2021 08:49:54 GMT+1200 (New Zealand Standard Time)
Service version: /powerbi/libs
报告正在使用基本身份验证进行本地连接。我们已经确认查询在使用相同凭据的所有三台服务器上运行良好。此报告使用直接查询，根本不使用分析服务。
深入研究我发现的 RS 日志：

这一行引起了我的注意：
Microsoft.PowerBI.DataExtension.Contracts.DataExtensionException: Failed to get CSDL. ---> MsolapWrapper.MsolapWrapperException: Failure encountered while getting schema
为什么要尝试运行 MSOLAP？
我可以：
- 使用与表相同的查询和凭据创建新报告 一个地图，它运行。
- 将相同的报告部署回 Dev 或 测试并运行。甚至在 Dev 上运行它并查询 Live。
RS 配置、防火墙设置、SQL 设置在所有 3 个服务器上都相同
到目前为止我读过的所有博客和帖子都导致了死胡同。 Kerberos，Windows Defender，缺少 DLL 并检查并与其他服务器进行比较，它们是相同的。
为什么这个报告不在这台服务器上运行？
编辑：我已经慢慢地从这份报告中剥离了内容。我删除了额外的标签，删除了所有过滤器、视觉效果和切片器，它仍然失败。我删除了唯一的查询并重新添加了相同的查询，使用相同的凭据选择相同的数据，现在它可以工作了。该错误似乎以某种方式附加到查询/模型。
解决方法
一个评论：错误号 5 是“拒绝访问”。忽略高位的类似于“5”的错误编号通常也是“拒绝访问”。即第 2 行中的 HResult = 0x80004005。
可能值得查看服务帐户的 NTFS ACL 之类的内容，尤其是在 MSOLAP 二进制文件文件夹中。
,不是答案，而是替代方案/解决方法。
我们最终创建了一个新的空白报告并将所有内容剪切并粘贴到其中。现在它可以运行了。
我们仍然不知道是什么导致它失败。
