This is an interesting feature that I have never used. Can you explain
how nginx does this "conversion". Most of write our own configuration
files. Are you using a commercial prodict?

This means nginx is ignoring your conflicting server names and not
incorporating them at run time. This is your clue.

Please run lsof -i :80 | grep -v nginx

This should tell you what other processes are bound to port 80.

Again, I think you are using one. Or believe that you are.
