Morning
After upgrading SQL Server and Reporting Services to 2019 the report viewer no longer displays on the web pages.
It appears as thought the web pages no longer recognise the report viewer control.
I have removed references to the old report viewer and installed the NuGet package for the latest version.
I have also updated the references in the web pages and web.config file.
Any suggestions on how to fix this?

Which SSRS version have to used before?
With SSRS version 2017 a very lot has changed and you have to setup nearly everything new; have you done all required steps? Is the SSRS service running?
It was something like 2012. It was removed and 2019 installed. All seems to be working. I can access report viewer in a browser locally and run reports fine. The problem is just when the reports are run from the web pages that have the report viewer control in them.

Are any error messages displayed? What browser are you using? I found a similar thread: https://stackoverflow.com/questions/33419047/report-viewer-control-not-showing-report-from-ssrs, maybe you can use it as a reference.
Best regards,

Morning Aniya
I have tried several browsers with the same result.
The web pages open fine and it looks as though it tries to call the report viewer but nothing is ever displayed.

To be honest, since we can’t check the status of your server in the forum, this type of issue is usually difficult to resolve. I suggest you consider using the phone support service provided by Microsoft which can usually help you resolve your issue.
