Hello,

We have an iFrame in Salesforce that directs to an IIS 7.x server running an asp.net site.  This has been working fine until earlier this week.  No changes on IIS server or site.


The site will render fine on Opera, Firefox and Edge browsers.

A look at the console shows one error being thrown: 

Access to manifest at 'https://hr-mysite.my.salesforce.com/visualforce/session?url=https%3A%2F%2Fhr-mysite--fhcm2.um5.visual.force.com%2Fresource%2F1595939225000%2Ffhcm2__collaborationportal%2Fmanifest.json' (redirected from 'https://hr-mysite--fhcm2.um5.visual.force.com/resource/1595939225000/fhcm2__collaborationportal/manifest.json') from origin 'https://hr-mysite--fhcm2.um5.visual.force.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.


Could this be preventing the page from being rendered?  I see the same message in the consoles of the other browsers, and they have no problem.

If that is not the issue, what steps do I need to take to debug further?

Thanks.
