1. Is it still starting?
A new server downloads about 10 GB before it starts, and downloads its mods on every start where the list changed. The Console tab shows the log: the server is listed once it prints "Server registered with address".
2. Search the exact name
Search for the full name as it is set in Deployment Settings, and clear the browser's filters: modded, passworded and full servers can all be filtered out.
3. Does it accept your platform?
A server set to PC only is invisible on consoles, and one set to PC and Xbox is invisible on PlayStation 5. Check Who can join in Deployment Settings.
4. Same version as your game?
After Bohemia releases an update, players on the new version only see servers that have updated too. The server updates every time it starts, so restart it from the dashboard.
5. Did a mod fail?
A mod ID the Workshop does not know, or one removed by its author, can stop the server starting. The log says which; remove it in the Mods tab.
Frequently asked questions
Why is my Arma Reforger server not in the server browser?
Usually it is still downloading on its first start, a filter hides it, it does not accept your platform, or it is on an older version than your game. Restarting it installs the latest version.
How long until a new Arma Reforger server is listed?
In our tests, under five minutes from the first start, most of it downloading the 10 GB server. Allow up to fifteen.
