Google announced in early 2020 that it will block content that is served via the insecure HTTP if the originating page uses HTTPS. The company decided to roll out the feature gradually by adding more and more file types to the blocklist. Executable files, e.g. .exe or .bat, are the first file types to be blocked, and the release of Chrome 86 put that block in place. Future versions of Chrome will block non-executable file types such as PDF, ZIP, or JPG files.
If you are hosting the file on http server then try to upload on https server. If you don’t have then try to upload Google Drive and convert the link to shared as public and this will solve the issue.
