Forge Server timed out

[Kryx5005]

Hi there,

So I've got a forge server that is running on my laptop with Linux. I am playing on it with 2 friends of mine. We are connected via Hamachi network. The problem is that they can't join to my server. When it first started it was ok. We were playing about a week on it, but yesterday they can't join. I still can play on it. When i start sever on new map it works fine, but on first map it doesn't work. We are trying lot of different things such as disabling proxy or firewall, creating new networks in hamachi, changing networks on PC (from home router to usb tethering in phone) changing versions of forge and updating mods. Console just says:

[Netty Epoll Server IO #2/ERROR] [FML]: NetworkDispatcher exception

io.netty.handler.timeout.ReadTimeoutException: null

and then disconnecting player. Here is the list of mods on server:

-chunk pregenerator,

-extra planets mod,

-galacticraft,

-galacticraft planets,

-MJRLegendslib,

-Micdoodle Core,

-TickDynamic,

-TreeCapitator,

-Buildcraft,

-Forestry,

-Industrialcraft 2,

-Just enough items,

We're using forge 1.12.2-14.23.5.2768 and server has 6GB of RAM allocated. I think that is all. And sorry for my crappy english.
