The causes of server problems aren’t always immediately obvious. The best place to start is the server output: Afterinfection doesn’t have an officially documented log file. So keep an eye on the output in the server window while it starts and runs. To access it, connect to your VPS using Remote Desktop.
If your server doesn’t appear in the server list, first check that it’s running and has finished starting up. Then check that the ports are open in the Windows Firewall and your VPS’s network firewall. You can find out which ports Afterinfection needs in Afterinfection: Set up a server on your VPS. According to community reports, the server only appears in the list if Steam is running on the VPS. Also make sure that no filters are active in the server list that could hide your server.
Restart the server using Remote Desktop and watch its window. Common causes include a server file that doesn’t match the current game version, a port already being used by another program, or insufficient memory. Also check whether Steam is running on the VPS. According to community reports, the server needs it.
Nothing ends a good session faster than an unexpected crash. Possible causes include an outdated server version, faulty mods, an overloaded VPS, or a configuration error. If a manually configured server crashes, it won’t restart automatically unless you’ve set up an automatic startup process or script yourself.
An outdated server often prevents players from connecting with a newer game version. Afterinfection isn’t available through SteamCMD. The developer publishes new server files in the game’s Steam news or on the game’s official Discord server. You’ll then need to replace the server file manually.
If you use mods or plugins, they’re a common cause of crashes, especially after a game update. Try disabling additional content and starting with a minimal configuration. If the problem goes away, add the content back step by step, testing after each change. This will help you pinpoint the cause.
Issues such as lag or delays often occur when the configuration isn’t suitable, the VPS doesn’t have enough resources, or mods overload the system.
Unsuitable settings or too many players can increase resource usage and cause lag. Afterinfection doesn’t provide an official description of the server configuration. If you’re having problems, first try reducing the number of players.
The operating system, Steam, and other programs on the VPS also need resources in addition to the server. You can check how heavily your VPS is being used in the ZapX dashboard under Monitoring. If the memory or CPU is consistently fully utilized, upgrading your VPS can help. Learn more in Upgrades, downgrades, renewals, and cancellations.
Ping spikes and lag are usually caused by limited VPS resources, a large number of players, or a server location far away from your players. First, check resource usage under Monitoring. If you suspect routing issues, see Diagnose network issues with WinMTR/MTR. If you still need help, contact our support team.
Game servers are occasionally targeted by DDoS attacks, which flood the server with traffic. Your VPS is protected by our DDoS protection. You can view past attacks in the DDoS Manager for your VPS in the ZapX dashboard, if it’s available at your location. If you suspect an attack is causing problems, contact our support team.
Regular backups can save you a lot of stress. Stop the server and copy its folder to a safe location. Your entire VPS is also backed up automatically every day. With an active ZapX Pass, you can restore these backups yourself and create your own. Learn more in Daily backups, restoring data, and restricted actions.
These steps should help you resolve the issue. If they don’t, don’t hesitate to contact our support team: simply start a Support Chat in your ZapX customer account. We’re here every day and happy to help! 🙂
