From today the server runs on Minecraft Java 26.3. To join you need that exact version: pick it in the launcher before connecting.
What changes for you
- You can only join with Java 26.3. Other versions and Bedrock are not supported.
- You need no mods: the server's resource pack downloads by itself when you join.
- The address stays the same: play.overwilds.com.
If you have trouble connecting, ask in the Discord support channel.
