Connection Lost : Internal exception: java.io.IOException: Bad packet id 83

With MSM 0.8.16, I am unable to connect to my server from the outside. I have properly forwarded 25565 on my OpenWRT enabled router and I still cannot connect to the server. I am using the latest minecraft server jar and the latest minecraft client.

Note: I have not seen this issue just using a plain old minecraft_server.jar by itself.

Can you connect to your minecraft server on your local network? Do a msm server restart (to display the startup info), then try connecting (whatever you did to generate that error), then attach your server.log (found in /opt/msm/server/$servername, or wherever you installed msm) and we can troubleshoot. The likely answer is you're using the "latest" msm minecraft, which ends up being 1.5.2, and you're connecting with a 1.6.2 client. You need pull #169 committed, if that's the case.

I have tried restarting it and changing certain options however nothing has worked. I can connect over local network and play with 4-5 players without problems.

well, if you can connect locally successfully, clearly it's not a client/server version mismatch. But on the flip side, if you can connect locally, it's also extremely unlikely it's a MSM issue. It's far more likely that something's wrong with your local network configuration, be it on the server or on whatever network devices you have between the server and the internet. Without more info we're going to have an extremely hard time troubleshooting it - I highly recommend you follow the advice in my previous post and attach your server.log after a restart and an attempt to connect that fails and generates the error you're seeing.

@masterblah777 it sounds like an issue with your network. Are you sure your ports are forwarded properly?

MSM only starts and stops your server. Therefor MSM cannot be responsible for errors on a running Minecraft server.
