SSRS 2017 reports having issues with IE 11? I'm experiencing symptoms very similar to what is described in this 2015 MSSSQLTips article: 

SQL Server Reporting Services (SSRS) is not compatible with Internet Explorer 11


  You upgraded to Internet Explorer 11, now when you preview a SQL Server Reporting Services (SSRS) report you find the print command is not visible in the report viewer. Also, sometimes when you change parameter values IE11 stops responding or it takes a long time to load the report. You may also find that the toolbar that displays the report controls and export features, appears on multiple lines when viewed with IE11. When you preview the same SSRS report in Chrome or Mozilla Firefox, it works fine without any issue, which means it is a browser compatibility issue. How can you make SQL Server Reporting Services (SSRS) compatible with IE11?


Virtually all discussion I can find of this problem refers to this article (or to a now-unavailable MS Connect page).

The problem is that the server-side fix suggested for SSRS 2008 doesn't work for SSRS 2017 (there is no &lt;meta http-equiv="X-UA-Compatible" content="IE=5"&gt; tag in the ReportServer\Pages\reportviewer.aspx file). 

Is there an equivalent server-side fix for SSRS 2017? Should I be adding this meta tag to this or a different ASPX file?

Other posts suggest upgrading SSRS, like this question about SSRS 2012, but I'm already on the next-to-last version of SSRS 2017 (14.0.600.689), and the change log for the more recent patch doesn't seem to contain any relevant fixes.

(A client-side fix isn't absolutely out of the question, but would involve a more difficult AD group policy push, so I'd prefer a server-side fix if there is one.)
try add

&lt;meta http-equiv="X-UA-Compatible" content="IE=EDGE"&gt;


tag in the ReportServer\Pages\reportviewer.aspx file.
