when you /who yourself do you come up as a Server OP?
If not then your not setting the status to 200 right.

Also RA had an issue like this back in 4.4 it turned out to be bad binaries.

I rember back a wile someone had this issue and it was because there addon.ini file wasnt being read right by the server.

May want to recompile everything just in case there was an error you missed if you cant track down the issue.
