Could not connect to localhost:8172: connection refused

My issue is similar to this one: #4

However, I did use the correct Lua version (5.1) from the beginning.

I compiled both LuaJIT-2.0.3 and the latest luasocket (3.0 rc1) with MinGW and embedded both into our application.
This is how luasocket is embedded (put into preload):

lua_getfield(_luascript->get_ptr(), LUA_GLOBALSINDEX, "package");
lua_getfield(_luascript->get_ptr(), -1, "preload");
lua_pushcfunction(_luascript->get_ptr(), luaopen_socket_core);
lua_setfield(_luascript->get_ptr(), -2, "socket.core");

The application is linked against the "socket.dll.3.0-rc1" (which is the weirdest name ever for a DLL...) and loads it just fine when the application starts.

I have also copied mobdebug.lua into our scripts folder. However, I get the error in the description as soon as I require("mobdebug").start().

I wanted to use luasocket-2.0.2 instead, but it seems that it cannot be compiled in MinGW without serious hassle, so I stopped trying.

By now, I managed to get luasocket-2.0.2 compiled. However, the error message is exactly the same.

Ugh, forget that. Windows blocked my debugging server.
