Friend cannot log in to server

[djalalytdin]

I created a forge server with mods for playing with a friend, at first everything was fine, but then it started to be thrown from the server.

in the window with the server this error was displayed NetworkDispatcher exception
io.netty.handler.timeout.ReadTimeoutException: null

later, a friend could not log into the server at all because of the same error. I tried to remove all the mods and delete our world, but it still can’t log into the server.

At the same time, everything is in order with me and I calmly play on the server.

We play through Hamachi, a direct tunnel is installed.

We both have good internet. With what it can be connected?

Here is a list of mods per server
