File Uploaded via FileManager are unable to Open


I found a very different kind of bug on Cyberpanel FileManager. Whenever a file is uploaded or unzip files from archive. It shows 403 error and also a 404 error on index.php or index.html file. Issue solves when I click on that subdomain parent folder and click on the Fix Permission button and the site starts resolving. But again if I upload any file same issue happens again to new and existing files on that subdomain or primary domain if the file is put under it.

This issue is not seen using FTP. Site works fine

How to resolve this? Any solution?

OS and CyberPanel version please
