DayZ servers do not download Workshop mods by themselves, so you add them yourself. Stop the server in the panel  before uploading.

Steps

1. Subscribe to the mods in the DayZ Launcher or Steam Workshop and launch the game once so they download as @ModName folders.
2. In Files, upload each @ModName folder to the server root.
3. In each mod folder, copy every .bikey from its keys folder into the server’s keys folder.
4. Add the mods to the server’s mod launch parameter, separated by semicolons. If your panel has an Additional Mods or startup field, use that.
5. Start the server.

Load order and keys

• Put dependencies first. Community Framework (@CF) usually goes at the top.
• A missing .bikey makes the server reject every player using that mod, or drop out of the public list.
• Some mods need extra server-side files, so read each mod’s page.
• If a mod adds items, you may need to merge its entries into types.xml, see loot.

Players

Everyone needs the same mods and versions. The DayZ Launcher prompts players to subscribe to missing ones. DayZ does not update Workshop mods automatically, so after a mod update, re-download and re-upload it.
