vibe.d no routes match path

[seany]

Please consider the code:


import vibe.vibe;
import std.conv;
import std.file;
import std.stdio;


ushort port   =  5502;






void main(char[][] args)
{

         auto router = new URLRouter;
         router.post("/archive", &savedata);
         router.get("/archive", &savedata); //also tested without 
this line

         auto settings = new HTTPServerSettings;
         settings.port = port;
         settings.bindAddresses = ["::1", "0.0.0.0"];
         listenHTTP(settings, router);

         runApplication();
}

void savedata(HTTPServerRequest req, HTTPServerResponse res) {


        // do things
                 return;

         }


This was working fine until yesterday

Today, it says (after a dub build) : 404 - Not Found

Not Found

Internal error information:
No routes match path '/a'

This is a production server. Is there anything i am doing wrong?
