Smartview Connection refused for REPORTS with Format

Summary:

Content (please ensure you mask any confidential information):

Hi all,

We are having an error "Connection Refused" when opening REPORTS with FORMAT insert or import, in smartview?

We are able to open add-hoc reports and open the same reports in the planning UI.

I have checked and enabled Webview2 to 12001 and also cleared cookies and enable Browser emulation for all.

I have checked this KM:

* Browser configuration: Oracle Support Document 2919770.1 (Smart View : Smart View Login Screen Continually Prompts With Error - "Connection Refused") can be found at: 

this is happening for all users within Citrix. Outside it we are able to open reports with Format.
