Multiplayer Portforwarding Server Issue

[Shike]

Hey all, hope someone can help me! I'm sure its a simple fix, but here's the gist: i've port forwarded 15124, and successfully too (when i have the Pokemon 3d server up and running, i use www.canyouseeme.org to see if the port 15124 is open, and i get this http://gyazo.com/69febb5e579444ae77064e8f353b2dc2 which means i have port forwarded successfully) Whenever i go into P3D and sign into Game Jolt, load my online profile, and then I go to join my server, there is no connection ( http://gyazo.com/11a74b18aeda5f17f1ec872fa3959fc8 ). Also, in the properties file of the server, i changed the IP address from 127.0.0.1 to my external IP i get from www.whatismyip.com. So as you can see, i'm a bit stuck! Any help would be greatly appreciated, thanks. - Shike
P.S. All of the IP's i blanked out are the same.
P.S.S i'm not sure what is causing the "[WARNING] Unexpected error while receiving client data: Object reference not set to an instance of an object." Could this be a/the problem?

You need to use the the server app that's provided if you haven't done so

When you say server app, do you mean the pokemon 3d server with the yellow icon instead of the green one? If so, i do have that running while trying to join.

Yes, that is it.

Yes, that is it.

I am using that, and it is up while i try to join, so i'm still in the same place..
