One user can complete curl request, different user cannot

In directory traversal lab I want to do ‘curl 142.93.35.92:31549/traversal/index.php?language=…/…/…/…/…/etc/passwd/’ but the curl request doesn’t complete and eventually times out. However another user running the same lab can do the curl request and it returns the expected output. I can successfully do ‘curl 142.93.35.92:31549/traversal/index.php?language=…/…/…/’ and that brings me to the /var/www/ directory. However if I include more than 3 …/ the request is unsuccessful.

Did you get any solution.

I am trying that using curl -s ---------------

but it’s returning nothing.
