Hi @Zolotoy ,
If you read the complete error message solution of this was in message. You have to add below given declaration in web.config HTTPHANDLERS section.

<add verb="*" path="Reserved.ReportViewerWebControl.axd" type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=15.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />  

Here is the e.g.:

 <system.web>  
    <httpHandlers>  
      <add verb="*" path="Reserved.ReportViewerWebControl.axd" type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=15.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />  
    </httpHandlers>  
  </system.web>  

Or declare the below given code in web.config in Handelrs section.

<add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=15.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />  

Here is the example:

  <system.webServer>  
    <handlers>  
     <add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=15.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />  
    </handlers>  
  </system.webServer>

Have you read the error message?

Your browser does not support scripts or has been configured not to allow scripts.

Which browser are you using and are scripts allowed to execute?

SSRS running in Local Mode

In local means, you have no SSRS server at all, only some RLDC reports rendering local?
