I have a server running on my laptop (Windows - I5 2nd Gen - 6gb of ram)

I run the server with the cmd batch and 4gb of ram only for the server. Run the server via Radmin Vpn to play with friends.

the command line is java -Xmx4096M -Xms4096M -jar forge-1.12.2-14.23.5.2847-universal.jar -o true nogui

 

We play about a month or maybe a little more without a problem. Just a few crash of the client and a few errors on cmd. But we didn't care about, because we open the client again and start playing again.

 

Today we experience a lot of crash on the minecraft client.

I started the server, everything load OK no problems. Just a common errors of missing recipe of 2 mods.

 

At the time we start the client, every mod is loading Ok no problems. At the main screen we click on multiplayer and enter the server we see loading terrain then suddenly minecraft closes and get an error. 

That happend to my friend and I, but now, i dont know why i can play (i play in my desktop computer).

 

This is what i see in the cmd screen when my friend try to connect:
