The causes of server issues aren't always immediately obvious. The best place to start is the server output: a running dedicated server displays its output in its console window, which you can access via Remote Desktop. For instructions on setting up the server, see Risk of Rain 2: Set up a server on your VPS.
As of November 2026, the Risk of Rain 2 Dedicated Server (SteamCMD app ID 1180760) does not provide any server files. If your server folder contains only _CommonRedist and an EmptySteamDepot file after the download, this isn't an issue with your VPS. You currently can't run your own server, so host a lobby in the game instead.
If your server doesn't appear, first check whether it's running and whether the server folder contains actual server files. Then check that the ports listed in the server configuration are open in your operating system's firewall and in your VPS's network firewall. Also make sure no filters are active in the server list that could hide your server.
Check whether the server folder contains a server executable. If it contains only _CommonRedist and EmptySteamDepot, there's currently no server to start. Common causes include a typo in the configuration, a port already in use by another program, or insufficient memory. If you've changed the configuration, try reverting the change.
Nothing cuts a good session short faster than an unexpected crash. Possible causes include an outdated server version, faulty mods, an overloaded VPS, or a misconfiguration. To get your server running again after a crash, restart it via Remote Desktop. If it keeps crashing, the cause is usually the configuration or mods.
An outdated server can cause crashes, unexpected behavior, or startup issues, and often prevents players from connecting with a newer game version. Updates aren't installed automatically. Stop the server and run the SteamCMD command +app_update 1180760 validate again.
Crashes are often caused by faulty or outdated mods and extensions, especially after a game update. Try disabling any additional content and starting with a minimal configuration. If the issue goes away, add the content back one piece at a time and test after each step. 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 extensions overload the system.
Unsuitable settings can increase resource usage and cause lag. Check the server settings, such as the player count, and restart the server after making a change.
The amount of memory and CPU your Risk of Rain 2 server needs depends on the number of players and your settings. The operating system and other programs on the VPS need additional resources. You can check how heavily your VPS is being used in the ZapX dashboard under Monitoring. If memory or CPU usage is consistently maxed out, 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 high number of players, or a server location far from your players. First, check usage under Monitoring. If you suspect routing issues, see Identify network issues with WinMTR/MTR. If you still need help, contact our support team.
Game servers are sometimes targeted by DDoS attacks that 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 issues, contact our support team.
Regular backups can save you a lot of stress. Before updating, back up the server folder containing your configuration. In addition, your entire VPS is automatically backed up daily. With an active ZapX Pass, you can restore these backups yourself and create your own. Learn more in Daily backups, restoring backups, and restricted actions.
These steps should help you resolve your issue. If they don't, feel free to contact our support team: simply start a support chat in your ZapX customer account. We're here for you every day and are happy to help! 🙂
