Seems like it's the Linux limitation[1][2]. Testing it myself, I made a directory "/home/bla/a", and inside this directory, a symlink that refers to "../a". After 41 invocations of "cd a", doing another "cd a" takes me to the root directory (so /home/bla/a). Perhaps when the web server tries to follow the 41st symlink the system says "You've recursed to much, go to /some/path/not/accessible/to/the/http/user" and that's why it returns a 403. And the directory (well, symlink) isn't listed at depth 40 because the server knows following it will lead to a 403.
