Autodesk Forge 跨域请求被阻止错误

Question

We have web applications where we use Autodesk Forge viewer. These were working as usual until yesterday. We didn't make any changes for months for some of them and now out of nowhere, we are receiving Cross-Origin errors. I have checked 3 of our web application with Forge, none of them are working: Firefox and Chrome give these kind of errors:

Access to XMLHttpRequest at 'https://developer.api.autodesk.com/modelderivative/v2/viewers/7.*/res/locales/en/allstrings.json' from origin 'WEBSITE NAME' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header has a value 'http://localhost:3000' that is not equal to the supplied origin.

Access to XMLHttpRequest at 'https://developer.api.autodesk.com/modelderivative/v2/viewers/7.*/lmvworker.min.js' from origin 'WEBSITE NAME' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header has a value 'http://localhost:3000' that is not equal to the supplied origin.

and more png loading problems with errors above.

I don't know if it is because of deployment platform heroku . I need help on this since I have no idea what has changed. On the one of the platforms, there were made no changes since last year but it stopped working also.

I am using this url to load the viewer:

https://developer.api.autodesk.com/modelderivative/v2/viewers/style.min.css?v=v7.*
https://developer.api.autodesk.com/modelderivative/v2/viewers/7.*/viewer3D.min.js

I need to mention that at localhost, Forge Viewer loads the model without CORS Error and works fine.

Thanks for the help.

Update:

According to @Can777, this issue was resolved by clearing browser history.

The problem is solved by deleting the browser histories from all browsers (Firefox nearly didn't have any history actually, since we only use chrome).
