If I run strace I see apps connecting @/tmp/.X11-unix/X0 first, and only if that doesn't exist, does the client try /tmp/.X11-unix/X0. The leading '@' indicates a NUL character requesting the abstract namespace. If /tmp/.X11-unix doesn't exist at all its possibly only listening on the abstract namespace, and not the normal namespace. There should be CLI args to change this behaviour when starting your X11 server.
