What you need before installing
Caveopolis 2 is a quest-focused modpack with custom recipes and progression. The current CurseForge release identified for this setup is version 0.12.1, built for Minecraft 26.1.2 on NeoForge. Its dedicated download is named Caveopolis_2_server_pack_0.12.1.zip and was released on September 28, 2026. Do not use a client profile or an older Caveopolis server archive in its place.
| Component | Required value | Why it matters |
|---|---|---|
| Caveopolis 2 | 0.12.1 | The server-pack files, mods, configs, and scripts must come from one release. |
| Minecraft | Java Edition 26.1.2 | NeoForge and the pack are version-specific. |
| Mod loader | NeoForge for Minecraft 26.1.2 | The server must load the same platform expected by the pack. |
| Java | Java 25 | Minecraft 26.1 requires Java 25; NeoForged documents the migration from Java 21 to 25. |
| Server files | Caveopolis_2_server_pack_0.12.1.zip |
This is the dedicated-server distribution, not the approximately 17.7 MB client ZIP listed on the project page. |
You also need permission to create files in the server directory, access to the host’s firewall, and (for players outside your home network) access to the router’s NAT or port-forwarding settings. Every player needs the same Caveopolis 2 release and matching Minecraft, NeoForge, and Java profile on their client.

Check Java before you create the server
Run java -version in a terminal or Command Prompt. The reported major version should be 25. A Java 21 installation can be valid for older Minecraft or NeoForge releases but is not the supported runtime for Minecraft 26.1. If several Java installations are present, make sure the java command used by your server script resolves to Java 25 rather than an older copy.
Download the correct Caveopolis 2 server pack
- Open the Caveopolis 2 project on CurseForge and go to its Files page.
- Select version 0.12.1 for Minecraft 26.1.2.
- Download the file named
Caveopolis_2_server_pack_0.12.1.zip. - Keep the ZIP intact until you have created the clean server directory. Do not rename a client ZIP and do not mix files from a different Caveopolis release.
The project page recorded 20,256 total downloads on September 28, 2026. That figure describes the project page’s download count, not a capacity estimate or a guarantee of server performance. The important installation distinction is the filename: only the dedicated server pack is intended to be copied into a server instance.
Create a clean server directory
Choose a folder used only for this world, for example Caveopolis2-server. Avoid placing it inside a launcher-managed client instance, and avoid reusing a directory that contains another modpack’s mods, configs, or world. A clean folder makes it possible to identify version mismatches and restore a backup without unrelated files.
On a Unix-like host, a typical workflow is to create the directory and enter it in a shell. On Windows, create and open the folder in File Explorer or use Command Prompt or PowerShell. The exact location is up to you; the NeoForge installer command accepts the installer JAR’s path.

Install NeoForge for Minecraft 26.1.2
- Download the NeoForge installer that corresponds to Minecraft 26.1.2. Do not select a NeoForge build for another Minecraft branch.
- Place the installer JAR somewhere you can reference from the terminal.
- From the intended server directory, run the documented installation command:
java -jar /path/to/neoforge-installer.jar --installServerReplace /path/to/neoforge-installer.jar with the actual path to the installer. The command creates the NeoForge server files and launch scripts in the current directory. If the command reports an unsupported Java version, stop and correct the Java installation before copying the modpack.
What a successful install provides
A successful NeoForge installation gives you a server directory containing the loader files and launch scripts. NeoForged’s server flow uses run.sh on Unix-like systems and run.bat on Windows. The first launch also creates files needed for EULA handling and runtime arguments.
Copy the Caveopolis server-pack contents into the server folder
- Extract
Caveopolis_2_server_pack_0.12.1.zipinto a temporary location. - Open the extracted server-pack directory and select its contents, including its
mods,config, scripts, and any other files supplied by the pack. - Copy those contents into the directory where NeoForge installed the server.
- When your file manager asks whether to merge folders, merge the pack’s folders into the NeoForge server directory. Do not create an extra nesting level such as
Caveopolis2-server/Caveopolis_2_server_pack_0.12.1/unless the archive itself explicitly requires it.
NeoForged’s guidance treats a server pack as a separate instance whose contents are moved into the server folder. A properly prepared server pack may already omit client-only mods. If it does not, remove client-only entries rather than allowing the dedicated server to load them. Mods that require a client rendering environment commonly produce a crash or a dedicated-server loading error.
Run the server for the first time
Windows
- Open the server directory.
- Double-click
run.bat, or execute it from Command Prompt or PowerShell so that you can read the log. - Wait for the initial process to stop. NeoForge’s documented first-run behavior is to halt so you can handle the Minecraft EULA.
Linux, macOS, and other Unix-like systems
- Open a terminal in the server directory.
- If necessary, make the script executable with
chmod +x run.sh. - Start it with:
./run.shLike the Windows script, the first run normally stops before the world becomes available. Keep the terminal output: the log identifies an incorrect Java runtime, missing files, or a mod-loading problem more precisely than a generic “server failed” message.

Accept the Minecraft EULA and launch again
- After the first run stops, open
eula.txtin the server directory. - Read the Minecraft EULA.
- Change
eula=falsetoeula=trueonly if you agree to the EULA. - Save the file without changing its name.
- Run
run.baton Windows or./run.shon a Unix-like system again.
The second launch should proceed into NeoForge’s mod and world initialization. The server is ready for connections only after the console reports that startup has completed and is accepting commands; do not close the process while it is generating the world.
Configure memory without guessing an official amount
No authoritative Caveopolis 2 source publishes a tested or official RAM allocation. Do not treat a fixed number as a supported requirement. NeoForge generates user_jvm_args.txt; use that file for JVM arguments, then monitor the server during actual play.
Change memory conservatively and observe whether the process remains stable while players explore, generate chunks, and run the pack’s progression systems. Leave enough memory for the operating system and other services on the machine. A server that starts successfully can still become unstable when the world is busy, so check the console and operating-system memory use rather than judging by startup alone.
Make the server reachable
Local network play
For players on the same home network, give them the host computer’s local IP address and the default Minecraft port, 25565, unless you deliberately changed it in server.properties. Test locally before exposing the server to the internet.
Rank #4
- Skins! We have biome settlers, city folk, town folk, and more!
- The Nether and all its inhabitants. Fight Ghasts and make friends with Pigmen
- Cross platform play for up to five players between Pocket Edition and Windows 10
- Revamped touch controls, controller support, and a controller mapping screen
- Enhanced Weather effects! Accumulating snow and more
Internet play
- Allow the server process or Java runtime through the host operating system’s firewall.
- Allow inbound TCP traffic on port
25565, the default Minecraft server port. - Configure the router’s port forwarding or NAT rule to send that port to the host computer’s local IP address.
- Give players your public address and port. If you changed the port, provide the changed value as
address:port.
NeoForged notes that firewall setup may be required. Router interfaces differ, so use the router’s own documentation for the exact NAT fields. A port-forwarded server is directly exposed to the internet; keep the operating system, Java runtime, NeoForge, and mod files maintained, and do not forward unrelated administrative ports.
Match every player’s client to the server
Each player should install Caveopolis 2 version 0.12.1 for Minecraft 26.1.2 with the same NeoForge profile. “Almost the same” is not enough: a different mod version, loader build, or configuration can cause a rejected connection, registry mismatch, missing recipe, or a crash during login.
- Use the same Caveopolis release shown in the server directory.
- Use Minecraft Java Edition 26.1.2, not another 26.1 patch or an older Minecraft version.
- Use the NeoForge profile expected by the pack.
- Install the client-side files from a trustworthy source such as CurseForge or Modrinth.
- Read the connection error before changing files; it often names the missing or mismatched mod.
Back up before changing anything
Stop the server cleanly before copying a world backup. Keep at least one known-good copy of the world and the server’s configuration, scripts, and mod list outside the live directory. Back up before updating NeoForge, replacing the Caveopolis pack, or changing major mod files. NeoForged explicitly warns that backups should be made before updates because a failed migration can damage or make a world unusable.
Label backups with the Caveopolis version, Minecraft version, NeoForge build, and date. If an update fails, restore the complete matching set rather than combining a newer mods folder with an older world and configuration.
Best Value
- Play and share with friends on console, mobile and Windows 10
- discover community creations in the new in-game store
- access new mini games and game modes through servers
Troubleshoot a server that will not start
The console reports the wrong Java version
Run java -version from the same environment used to start the script. If it is not Java 25, correct the system PATH or call the Java 25 executable explicitly from your launch process. Minecraft 26.1 will not have a supported runtime on Java 21.
NeoForge loads, but the pack’s mods fail
Confirm that the installer and the pack both target Minecraft 26.1.2. Then compare the server directory with the extracted Caveopolis_2_server_pack_0.12.1.zip contents. A missing mods folder, an extra nested folder, or files copied from another release can all produce dependency or registry errors.
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →A client-only mod is being loaded on the server
Inspect the server log for a mod that requires a client display, renderer, or other client environment. Remove that client-only mod from the server’s mods directory if the server pack did not already exclude it. Do not remove a mod merely because its name is unfamiliar; verify its role and dependency information first.
The server stops immediately after the first launch
Check whether eula.txt exists and whether it contains eula=true after you have accepted the EULA. If the file is correct, read the earliest error in the console rather than the final shutdown line; the first exception usually identifies the underlying issue.
Players cannot connect
- For local players, verify the host’s local IP and that the server is actually running.
- For remote players, verify the firewall rule and router NAT forwarding for TCP port 25565.
- Confirm that the server is not behind a second router or carrier-grade NAT that prevents inbound forwarding.
- Check that clients use Caveopolis 2 0.12.1, Minecraft 26.1.2, and the matching NeoForge profile.
- Use the server console to see whether the connection reaches the host and is rejected for a mod mismatch.
The server runs out of memory or becomes unstable during play
There is no Caveopolis-specific official RAM figure to apply blindly. Review user_jvm_args.txt, the operating system’s available memory, and the server log. Increase or reduce the configured allocation in small steps while leaving headroom for the operating system, and test the same activity that triggered the problem. If instability began after a mod or loader change, restore the pre-change backup before tuning memory further.
Self-hosting compared with managed hosting
Self-hosting gives you direct access to the files and network but makes you responsible for installation, updates, backups, firewall rules, and uptime. A managed Minecraft modpack host can take over some infrastructure tasks, but you must confirm that its control panel supports Java 25, Minecraft 26.1.2, NeoForge, direct server-pack ZIP uploads, and world backups before committing. The available evidence does not establish a Caveopolis-specific provider, current prices, player-capacity benchmarks, or performance rankings.
