If Arma 3 launcher only shows some of your server mods, the server may not be sending enough mod metadata to the Steam client. Increase steamProtocolMaxDataSize in server.cfg, then restart the server.
- Open your Arma 3 server in the control panel.
- Click Configuration Files.
- Open
server.cfgwith Text Editor. - Find
steamProtocolMaxDataSize.
- Increase the value. Start with
2048, then increase in 2048 increments for larger mod lists. - Click Save & Exit.
- Restart the server and refresh it in the Arma 3 launcher.
Example:
steamProtocolMaxDataSize = 8192;
This does not install missing mods by itself. It only increases how much mod information the server can advertise to the launcher.
