I have the same issue with my server on windows.
Since 1.30 no message that is set in messages.xml is shown.
Worked fine the morning before the Update.

If you need only welcome message you can use that workaround

Edit init.c

Add code below to class CustomMission

        override void InvokeOnConnect(PlayerBase player, PlayerIdentity identity)
        {
                super.InvokeOnConnect(player, identity);
                GetGame().GetCallQueue(CALL_CATEGORY_SYSTEM).CallLater(SendWelcome, 5000, false, player);
        }

        void SendWelcome(PlayerBase player)
        {
                if (player && player.IsAlive() && player.GetIdentity())
                {
                        string name = player.GetIdentity().GetName();
                        player.MessageFriendly("Welcome to the server, " + name + "!");
                }
        }

And you can use different colours

1. MessageStatus

2. MessageAction

3. MessageFriendly

4. MessageImportant

I am having the exact same problem with the messages.xml. I have tried unmodded and modded. I have reinstalled multiple times and used different PCs. I have verified files. The same messages.xml works perfectly on a windows 11 PC running the server. But on a Linux PC, No messages and no shutdown. The log file has it listed, so the server knows it is there. I have tried hosting all the offical maps with no result.

Same issue here. Running linux. No mods.

I've tried every possible method to get server messages working. Everything works perfectly fine on Windows, and the XML files are read without any issues. However, on Debian 13, nothing works after the 1.30 update. I've tested every method I could think of, checked the files and permissions, and still got zero results. 😕 After rolling back to DayZ version 1.29, all server messages are working perfectly again. The issue only occurs on version 1.30 running on Debian 13.

Does anyone have any idea what could be preventing the game from reading the messages.xml file on Linux? Could something have changed in the way the game handles server messages in the 1.30 update?

Any suggestions or insights would be greatly appreciated!
