space in url giving file not found error in browser

Physical folder having space: /about us/contactus.php

when we enter in browser https://www.example.com/about us/contactus.php
It will auto convert URL to https://www.example.com/about%20us/contactus.php

earlier it was working fine but after migrating to new server with same apache and php version,
it is giving error of file not found.

Rest of files working fine where there is no any space.

No any change in .htaccess hence require setting to do in either apache or php

It would great help if anyone can guide.
