Server issues can have many different causes, which aren’t always immediately obvious. Learn how to analyze common issues step by step and keep everything running smoothly.
General issues can include all kinds of unexpected problems that don’t fit into a specific category. They’re often related to basic settings, missing files, or simple misconfigurations. These can usually be fixed quickly with a few checks and adjustments.
If your server doesn’t appear in the list, it may be because initialization didn’t complete successfully. This can happen, for example, due to a faulty configuration or corrupted files. You can usually find more information in the server console or log files. You should also make sure there are no incorrect filters enabled in the server list that could prevent your server from appearing.
Nothing ends a good session faster than an unexpected crash. Crashes can be caused by faulty server software, broken or incompatible extensions (such as plugins, mods, resources, or frameworks), system overload, or misconfigurations.
Always running the latest version of your game server is essential for stability, security, and compatibility. Otherwise, game updates, framework changes, or updates to third-party tools can cause serious issues if your server is outdated.
An outdated game server can cause crashes, unexpected behavior, or even startup issues.
Crashes are often caused by faulty or outdated extensions. Whether it’s a framework, plugin, mod, or resource, issues can occur when an extension isn’t compatible with the current game version or has bugs in its code.
This can lead to unexpected server crashes, freezes, or errors, especially when multiple problematic extensions interact. If you suspect an extension is the cause, temporarily disable it and check whether your server remains stable. This helps you quickly identify which extension is causing trouble.
Make sure all the extensions you use are up to date, actively maintained, and tested for compatibility with your game version to avoid crashes and downtime.
To isolate the cause of crash issues, it often helps to temporarily disable additional content. Start with a minimal configuration and check whether the problem persists. If it doesn’t, add extensions, mods, or resources back one at a time, testing after each step. This helps you pinpoint the item causing the issue. This approach saves time and relies on facts rather than guesswork.
Smooth server performance is essential for a good gaming experience. Issues such as lag, delays, or sudden crashes often occur when the server configuration isn’t optimal, the hardware isn’t suitable, or installed extensions overload the system.
Common causes include poor configuration, insufficient resources, or unoptimized plugins and mods. Checking and adjusting these areas can resolve most performance issues and keep your game stable and responsive.
Incorrect or poorly adjusted server settings can increase resource usage and cause performance issues such as lag or stuttering. Make sure your configuration values match the recommended settings for your game and server size. Review and adjust them as needed to help your server run as efficiently as possible.
You can easily adjust your configuration in the Configuration tab — an AI will automatically display the appropriate settings as form fields, or you can edit the raw text of the config file directly.
To keep your game server running smoothly and reliably, it’s important to choose a configuration that suits your project. Requirements vary significantly depending on the game, the use of extensions such as mods, plugins, or resources, and the expected number of players.
ZAP-Hosting provides a recommended minimum configuration during the ordering process. This is based on typical use cases and is intended to help you avoid common performance issues such as lag, crashes, or long loading times.
Follow these recommendations or scale up if needed to ensure optimal stability and the best experience for you and your players. This is a minimum recommendation.
Depending on the scope of your project and the amount of additional content, you may need more resources from the start, or your needs may increase over time. In these cases, upgrading your game server package is the easiest way to ensure performance and stability.
Not all extensions are optimized for performance. Whether it’s a framework, plugin, mod, or resource, poor implementation can cause significant performance issues on your server. The functionality may work, but the code might be inefficient, overly complex, or put unnecessary strain on server resources.
This can lead to high CPU usage, memory leaks, lag, or even crashes, especially when multiple unoptimized components interact. Make sure extensions are actively maintained, well documented, and tested for performance. If in doubt, community feedback or monitoring your server’s performance can help you identify the source of the problem.
To isolate the cause of performance issues, it often helps to temporarily disable additional content. Start with a minimal configuration and check whether the problem persists. If it doesn’t, add extensions, mods, or resources back one at a time, testing after each step. This helps you pinpoint the item causing the issue, whether it’s a conflict, memory leak, or excessive resource usage.
This approach saves time and relies on facts rather than guesswork.
Network issues can cause lag, delays, or disconnections. They can have many different causes, but are usually fixable with the right settings and security measures.
Ping spikes, lag, and network delays are usually caused by limited server resources, such as insufficient CPU power, RAM, or bandwidth.
They can also occur when the server is overloaded by many players or resource-intensive scripts and plugins. Network issues such as poor routing, external congestion, or a server location far from your player base can further increase latency.
Background processes, unstable internet connections, packet loss, and outdated or incorrectly configured server software can also cause noticeable performance issues during gameplay.
If your server is experiencing lag or high ping, there are a few simple steps you can take to improve performance. First, make sure your server meets or exceeds the recommended specs for your game and project. Choosing a server location close to your player base can also help reduce latency.
If you suspect routing issues or external network problems are the cause, don’t hesitate to contact our support team. We’ll help you analyze the situation and find the best solution.
Game servers can occasionally be targeted by malicious network attacks, especially Distributed Denial of Service (DDoS) attacks. These flood the server with an extremely high volume of traffic, causing lag, connection loss, or even complete downtime. Attackers may also try to exploit network vulnerabilities or disrupt server stability through repeated connection attempts or unusual data patterns.
Most of these threats are outside the control of a regular user, but ZAP-Hosting provides built-in protection and mitigation measures to help protect your server from common and advanced attacks. If you suspect your server is under attack and experiencing issues, contact our support team for help and next steps.
Regular backups can save you a lot of stress and hassle. Create backups regularly so you can restore an older, working version if something goes wrong. We already back up your game server automatically every day. With the ZapX Pass, you can also create your own backups at any time and restore them with a single click — with ZapX Pass Pro, you can even automate backups on your own schedule. Find out more in our guide to backups.
These steps should help you resolve your issue. If your issue is listed here, the relevant solution will usually point you in the right direction and get your server running again quickly.
If not, don’t hesitate to contact our support team. We’re here for you every day and will be happy to help! 🙂
