Webframe not loading cross frame content

Hi,

I want to load some other application webpage into a Mashup and used Webframe widget for the same.But whenever I try to load mashup,getting below error.

“Refused to frame 'https://myWebsite/dashboards' because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'self'".

As per the suggestion (Display Mashups from external Browser - PTC Community)

uncommented the filter in tomcat web.xml and now getting new error as shown below.

"Refused to display 'https://myWebsite/dashboards' in a frame because it set 'X-Frame-Options' to 'deny'.

Specs: Thingworx 8.5.4 Chrome Browser
