Getting a Minecraft server up and running can be a rewarding experience, but the setup process comes with its own set of challenges, especially when mods, configs, and version compatibility are involved. If you're struggling to connect to your server, configure it correctly, or even get it to start, you're not alone. Most setup issues come down to a handful of common causes that are straightforward to resolve once identified.

Here are some of the most frequent setup-related issues players and server owners run into:

Can't connect or can't find the server in-game - this is often caused by an incorrect server address, the server not being fully started yet, a firewall or port blocking the connection, or the server being offline. Double-checking your server IP and ensuring it's actively running are good first steps.
Difficulty with server setup or config changes - editing configuration files, adjusting settings, or getting the server to behave the way you want can be confusing, particularly for first-time server owners. Misconfigurations in files like server.properties or mod-specific configs are a common stumbling block.
Can't do what I want with my server - If your server isn't behaving the way you'd like, it's usually down to one of two things: not having access to the right modpack, or not having enough resources allocated to support what you're trying to run. If the modpack you want isn't available through the control panel, you can still get it running by installing it manually. If your server is struggling to handle your setup, you may need to upgrade your plan or allocate more RAM or CPU priority to keep things running smoothly.
Outdated server or modpack version - running an outdated modpack can cause compatibility issues, missing features, or even prevent players from joining altogether. If your modpack is out of date, you'll need to update it manually. This involves backing up your world, resetting your server files, and reinstalling the latest version of the modpack. For a full step-by-step walkthrough, see our guide: How to Update Modpacks Installed on Your Server.
Server won't start - startup failures during initial setup are typically caused by misconfigured server files, a Java version mismatch, port conflicts, or an incomplete installation. Reviewing your server console logs is the best way to pinpoint the exact error.

This article will walk you through each of these scenarios to help you identify what's going wrong and get your server set up successfully.

#Can't Connect or Can't Find the Server In-Game

If you're having trouble connecting to your server or it isn't showing up in-game, the most common causes are an incorrect server address, the server still starting up, or a firewall/blocked port preventing the connection. Before troubleshooting further, make sure your server IP is correct and that the server is fully online. Consider checking out these guides to help you with these issues:
