A $DISPLAY setting of 127.0.0.1:0 means that clients will connect to
TCP port 6000 on 127.0.0.1, whereas a setting of :0 means that they
will connect to the Unix-domain socket /tmp/.X11-unix/X0.
If the former works, but the latter doesn't, possible explanations
include the server not creating or listening on the Unix-domain
socket, or the client being unable to connect to it (e.g. due to
filesystem permissions or /tmp using a tmpfs which makes files
invisible to users other than their owner).
Also, on some OSes, transports other than Unix-domain sockets (e.g.
various types of STREAMS pipes) may be used for local displays.
Do you get any error messages from the client when trying to connect
with DISPLAY=:0.0? They may provide a clue as to why the connection
