Hello, first time here!
I've been hosting Minecraft servers on my pc for my friends for the past 3 years, with no problems from my router. However, since 2 days ago, every time a user joins from a specific IP (2 siblings play on my server that cause this problem but other users do not) it completely disconnects my pc from the network and hides the connection so I cannot reconnect until reboot.
I am running a Windows 10 desktop with an ethernet connection, and the Minecraft server is a 1.10 forge server.
I have never experienced this type of error before, nor are there any errors in my server logs that would indicate a problem on that end.
The only reason I have come up with as for why this could be happening is maybe the router thinks their connection is dangerous and disconnects my pc from the network to prevent compromise? I don't know how I would check that sort of thing.
Solved! Go to Solution.
Sounds more like the device connecting from that address is infected with malware.
We checked with various anti malware programs and none found any such problems on either end
After some testing and educated guessing, I have found that the issue was the latest version of my ethernet driver. After rolling back, the issue has been resolved
