Issues and solutions
Server issues can have many different causes, which aren’t always immediately obvious. Learn how to analyze common problems step by step and keep everything running smoothly.
General
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 configuration errors. These can usually be fixed quickly with a few checks and adjustments.
Server not visible
If your server doesn’t appear in the list, it may be because initialization didn’t complete successfully. This can be caused by an incorrect configuration or corrupted files, for example. You can usually find more information in the server console or log files. You should also make sure that no incorrect filters are active in the server list that could prevent your server from being displayed.
Crashes
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 configuration errors.
Keep your server up to date
Keeping your game server up to date is essential for stability, security, and compatibility. Game updates, framework changes, or adjustments to third-party tools can otherwise cause serious problems if your server is out of date.
An outdated game server may crash, behave unexpectedly, or even fail to start entirely.
Faulty or problematic extensions (frameworks, plugins, mods, resources)
Crashes are often caused by faulty or outdated extensions. Whether it’s a framework, plugin, mod, or resource, problems can occur when an extension isn’t compatible with the latest 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 to blame, try disabling it and check whether your server remains stable without it. This is a quick way to find out which extension is causing problems.
Make sure all the extensions you use are up to date, actively maintained, and tested for compatibility with your game version to prevent crashes and downtime.
To narrow down the cause of crashes, 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 exactly which component is causing the issue. This approach saves time and helps you rely on facts instead of guesswork.
Performance
Smooth server performance is essential for a great gaming experience. Issues such as lag, delays, or sudden crashes often occur when the server configuration isn’t optimal, the hardware doesn’t meet the requirements, or installed extensions overload the system.
Common causes include incorrect settings, missing resources, or unoptimized plugins and mods. Checking and adjusting these areas can resolve most performance issues and keep your game stable and responsive.
Poor server configuration
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 config file text directly.
Game requirements not met
To ensure your game server runs smoothly and reliably, it’s important to choose a configuration that suits your planned project. Requirements vary significantly depending on the game, the use of extensions such as mods, plugins, or resources, and the expected number of players.
During the order process, ZAP-Hosting provides a recommended minimum configuration. 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.
Be sure to follow these recommendations or upgrade as 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 as your project grows. 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 feature may work as intended, but its execution could be inefficient, overly complex, or unnecessarily demanding on server resources.
This can lead to high CPU usage, memory leaks, lag, or even crashes, especially when several unoptimized components interact. Always 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 potential causes.
To narrow down 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 exactly which component is causing the issue — whether it’s a conflict, memory leak, or excessive resource usage.
This approach saves time and helps you rely on facts instead of guesswork.
Network
Network issues can cause lag, delays, or dropped connections. There are many possible causes, but the right settings and security measures can usually resolve them.
Ping spikes, lag, and network delays
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 a large number of players or resource-intensive scripts and plugins. Network-related issues such as poor routing, external congestion, or a server location far from your player base can also increase latency.
Background processes, unstable internet connections, packet loss, and outdated or incorrectly configured server software can also cause noticeable performance issues in the game.
If you notice lag or high ping on your server, you can take a few simple steps 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 disruptions, don’t hesitate to contact our support team. We’ll help you analyze the situation and find the best solution.
DDoS and other network threats
Game servers can occasionally be targeted by malicious network attacks, particularly Distributed Denial of Service (DDoS) attacks. These flood the server with traffic, causing lag, connection loss, or even complete downtime. In other cases, attackers may try to exploit network vulnerabilities or disrupt server stability through repeated connection attempts or unusual data patterns.
Most of these threats are beyond the control of a typical user, but ZAP-Hosting offers built-in protection and mitigation systems to protect your server against common and advanced attacks. If you suspect your server is under attack and it’s causing problems, contact our support team for help and next steps.
