Openshift Minecraft Server timeout - server

Question

I recently made an Minecraft Server on Openshift with this Tutorial.
After I made the port forwarding, I was able do get a Connection in Minecraft to my Server. But I cannot login! It simply ends with the Message: Timed-Out.
In the Server logs I only see, what I know: I lost my connection. Here are the logs:

Answer 1

java.io.IOException: Bad packet id 72 deals will a malformed packet. I've read where it could mean anything from not specifying the correct port to trying to connect with incompatible mod versions.
In your case, it looks like you are explicitly defining the server-ip in your server.properties. In the starting logs:
2016-01-01 17:29:18 [INFO] Starting Minecraft server on 127.2.1
127.2.1 is not a valid address, so it makes sense to me that packet transmission would be malformed. Leave this field blank (as it is by default) or provide a valid IPv4 address.
I feel pretty confident that is what is going on because the tutorial your provided makes you set this field as well.

Answer 2

Bad packet id 72 means that you are trying to login to a server that's port isn't configured correctly. in the log, you have mentioned 2016-01-01 17:29:18 [INFO] Starting Minecraft server on 127.2.1.
solution:
(I have configured my test server to similar to yours)
1. go to server.properties and in server-ip:section, remove the content after that. That will make it the default ip
go to your router home page and port forward the server to 25565
it should now work
Good luck on your new server! :)
