I'm trying to have a friend join my Minecraft server. For some reason, when he joins the server, his avatar just stays in one place and then after about 15 seconds he is kicked off the server. The weird thing is, he is able to move around on his end for a little bit but all I see on my end is him trapped in one spot.
We both have official Minecraft licenses (As I paid for them both) and are playing on the latest version. The server is a Linux server running on AWS and is running the java dedicated server version 1.16.5. I've been using this server successfully with other players for over a year and I haven't seen this problem. No firewall rules are enabled on the server. I'm wondering if there is some setting that I'm missing. Any ideas?
