It is always that same IP, and while playing in the server, I keep on seeing "left the game" without a name. It happens every two minutes or so, since 3 weeks.
I have tried to ban the IP by adding it in the banned-ip.txt file and in the banned.txt file, but it keeps on happening.
I am currently hosting a server, and since I started it around 3 weeks ago, I keep on seeing lines in the console saying :
/83.13.18.154 connected
/83.13.18.154 lost connection suddenly. (java.io.IOException: Badcommand: 19)
/83.13.18.154 disconnected
It is always that same IP, and while playing in the server, I keep on seeing "left the game" without a name. It happens every two minutes or so, since 3 weeks.
I have tried to ban the IP by adding it in the banned-ip.txt file and in the banned.txt file, but it keeps on happening.
Please help.
Here is a picture of what I see in the console :
