Some pages wil not display i get ERR_FILE_NOT_FOUND

Some web pages will not display, whether on the web or HTML file on my PC C:\ drive. I get a blank page and the error message …“ERR_FILE_NOT_FOUND”. The file is there and I can go to MS Edge and open the webpage or file with no problem.

Is it security/privacy protocols or are required plugins not installed? Something else???
