Introduction
Setting up and running your own Factorio game server can be exciting and a lot of fun. It’s a great way to build a custom gaming environment and community, but it also means taking responsibility when things go wrong. Crashes, lag, and configuration issues are common challenges that every server owner will face at some point.
To help you spend less time troubleshooting and more time enjoying your server, we’ll cover the most common issues server owners encounter and provide solutions so you can fix them quickly and effectively.
FAQ
Frequently asked questions
Initialization may not have completed successfully, perhaps because of an incorrect configuration or corrupted files. Check the server console or log files, and make sure no incorrect filters are enabled in the server list.
Common causes include faulty server software, broken or incompatible extensions (frameworks, plugins, mods, or resources), system overload, or misconfigurations. Try disabling suspicious extensions to narrow down the cause.
Common causes include limited server resources (CPU, RAM, or bandwidth), overload from many players or resource-intensive extensions, routing issues, or a server location far from your player base. First, check whether your server meets or exceeds the recommended specs.
Most network threats are outside your control, but ZAP-Hosting provides built-in protection and mitigation systems. If you suspect an attack, contact our support team for help and next steps.
Create regular backups 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 and restore your own backups at any time — and with ZapX Pass Pro, schedule them automatically.

Issues and solutions
Server issues can have many different causes, and they’re not always immediately obvious. Learn how to troubleshoot common issues 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 misconfigurations. A few checks and adjustments are usually enough to fix them quickly.
Server not visible
If your server isn’t visible, 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 enabled in the server list that might prevent your server from appearing.
Crashes
Nothing cuts a good session short 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.
Keep your server up to date
Running your game server on the latest version is essential for stability, security, and compatibility. Game updates, framework changes, or changes to third-party tools can otherwise cause serious issues if your server is out of date.
An outdated game server can cause crashes, unexpected behavior, or even startup issues.
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 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 causing the issue, try disabling it and check whether your server remains stable. This makes it easier to identify which extension is causing problems.
Make sure all the extensions you use are up to date, actively maintained, and tested for compatibility with the current game version to avoid 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 issue persists. If it doesn’t, add extensions, mods, or resources back one at a time, testing after each change. This helps you pinpoint exactly which component is causing the problem. This approach saves time and helps you troubleshoot based on facts rather than guesswork.
Performance
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 doesn’t meet the requirements, 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.
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 automatically displays suitable settings as form fields, or you can edit the raw text of the config file directly.
Game requirements not met
To ensure your game server runs smoothly and reliably, it’s important to choose a configuration that suits your project. Requirements vary widely depending on the game, your use of extensions such as mods, plugins, or resources, and the number of players you expect.
ZAP-Hosting provides a recommended minimum configuration during checkout. It’s 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 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 feature may work as intended, but its implementation could 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. Always make sure extensions are actively maintained, well documented, and tested for performance. If you’re unsure, feedback from the community or monitoring your server’s performance can help you identify the source of the problem.
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 issue persists. If it doesn’t, add extensions, mods, or resources back one at a time, testing after each change. This helps you pinpoint exactly which component is causing the problem — whether it’s a conflict, memory leak, or excessive resource usage.
This approach saves time and helps you troubleshoot based on facts rather than guesswork.
Network
Network issues can cause lag, delays, or disconnections. They can have many different causes, but can usually be resolved with the right settings and security measures.
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 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, 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 problems, 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 sometimes be targeted by malicious network attacks, especially Distributed Denial of Service (DDoS) attacks. These flood the server with excessive 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.
While most of these threats are outside the control of regular users, ZAP-Hosting provides built-in protection and mitigation systems to help protect your server against common and advanced attacks. If you suspect your server is under attack and experiencing issues, contact our support team for help and further instructions.
Preventive measures
Regular backups can save you a lot of stress and hassle. Create backups regularly so that you always have an older version to restore 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 click — with ZapX Pass Pro, you can even schedule automatic backups.
