Hello,
I bought a Forge 1.20.1 server and installed some mods to play with friends. The server specs are 3 cores and 12GB of RAM, hosted in France by Minestrator. At most, four of us play simultaneously. There isn't much on our world—no large farms, no Create automation—and we typically use a maximum of 4GB of RAM while playing. I’ve hosted multiple servers with Minestrator before without any issues.
The problem:
Whenever I or other players enter specific areas, everything bugs out. No commands or actions work, and after a few seconds, everyone gets timed out. We can only reconnect after about 30 seconds.
This only happens in certain zones—sometimes 500 blocks away from our bases, sometimes 3000 blocks in another direction. However, exploring the Nether causes no issues.
When we reconnect, we’re set back about 5 minutes, with some actions undone while others remain. It’s quite inconsistent.
I’ve attached the server logs for reference.
