Minecraft Lan world connection error

So me and my friend want to play modded Minecraft over lan. Yes we are in the same house we are on same WiFi. Laptop 1 is the host and has McAfee installed and laptop 2 doesn’t. Laptop 1 is the host as its stronger, but every time laptop try to connect to the host it gets stuck in encrypting and gets the error- Internal Exception: Java.I’m.IOException: An existing connection was forcibly closed by the remote host I have tried everything turning off the firewalls, adding the ip of laptop 2 to laptop 1s McAfee settings https://vidmate.onl/ , updating and restarting, removing all the mods and trying on vanilla Minecraft, allowing Java connections through where ever I can, I have tried everything but I can’t seem to stop the error. Worst part is if Laptop 2 host laptop 1 can join the hosted world no problem. But since it’s older and weaker this isn’t viable. Does anyone have any idea on a solution for this problem?

Hi @dadya06,

Greetings from McAfee.

Kindly try to enable the port number 3389 from firewall settings in the McAfee application. Also try to force the ICMP ping request from the firewall settings.
