Step-by-Step Troubleshooting Guide for Zenless Zone Zero Server Connection Timeout

You think Zenless Zone Zero is a single-player game? No no no. While miHoYo's three major titles all primarily focus on single-player gameplay, they all require players to maintain a constant server connection. This is to prevent cheating and ensure data security.

So, you will very likely see a server connection failure notification after hitting the login button. Yes, the lengthy shader loading won't ultimately lead to a good outcome. In more severe cases, you may not even be able to connect to the launcher properly. However, this issue is rarely caused by miHoYo's servers going down. It is more likely related to network connection restrictions, VPN and proxy interference, or local device issues.

Quick Steps

1. Check local network bandwidth and device performance status
2. Check if the server is running normally
3. Check if the network connection needs optimization
4. Disable proxies, update the game, and select the correct server

If you need a more detailed solution, please check the specific steps below.

Fix 1: Reduce Local Device Impact

miHoYo has previously acknowledged this issue: when system load is high on PC, the login handshake process is particularly fragile. This mainly manifests as:

• Running too many programs during gameplay, consuming system resources
• Local network bandwidth being heavily occupied, such as by streaming or live broadcasting
• The device being in power-saving mode, limiting performance output

In short, your device is not fully dedicated to the Zenless Zone Zero experience. What you need to do is close these unnecessary programs and enable the performance mode on your PC.

This issue is also unavoidable on mobile devices. Prolonged gaming sessions, background apps consuming resources, and constantly searching for weak network signals can cause overheating, which indirectly leads to performance degradation and subsequent server data exchange failures.

Fix 2: Could the Problem Be on the Server Side?

Yes, but the probability is very low. Objectively speaking, miHoYo's servers are known for their stability among online games. Although their server deployment is not extremely widespread, the probability of downtime is very low.

Furthermore, the game's operations team responds very quickly to emergencies. Version updates are usually announced a week in advance, and unexpected outages are communicated through various channels within a short period of time, minimizing the chance that players encounter server connection failures without any notice.

So, if you have concerns, simply check Zenless Zone Zero's official accounts across various channels for the latest information.

But if the servers are running normally, where is the problem coming from?

Fix 3: Check Network Connection Status

This is the most likely cause. Your game data may not even be reaching the server. Start with the simplest network diagnostic:

• Press the shortcut Win + I to open Settings.
• Click Network & Internet on the left.
• Click Advanced network settings on the right.
• Find and click Network troubleshooter (or go to "System" > "Troubleshoot" > "Other troubleshooters" > click Run next to "Network and Internet").
• See if there are any error notifications. If so, restart your router first and check if the Ethernet cable is properly connected. If not, the problem lies with the public network.

You can contact your ISP to find out if there are network outages in your area, and then try using GearUP to optimize routing nodes. This step addresses data transmission issues over the public network. In fact, even if the ISP is functioning normally, your data may not be getting optimal transmission, because the general-purpose network needs to consider overall usage rather than specifically optimizing connections to miHoYo's servers for you alone.

GearUP

This is exactly why GearUP is needed. It can quickly help you adjust the connection path and resolve the issue without changing any network settings, in just two steps on PC:

1. Search for Zenless Zone Zero in GearUP.
2. Enable optimization, then launch the game.

Even on mobile devices and PCs, you can choose GearUP Mobile and the GearUP router plugin, respectively.

Some Easily Overlooked Issues

Use of Network Proxies

miHoYo specifically warns users not to use general-purpose VPNs and proxies to access its games. If the server detects an abnormal route, it may block login. This is mainly related to regional server policies. Although it may seem less user-friendly, for compliance reasons, it is best to disable them.

Server Region and Version Issues

As mentioned above, the reason for the constant server connection is that the official team needs to ensure the integrity of the gacha mechanism, event reset mechanisms, and world state synchronization. This also includes balance adjustments brought by each version update. For example, you cannot use a version 2.8 client to connect to a version 3.1 server.

Typically, the launcher will notify you that a game update is required, but if you are unsure, you can still click to check for updates.

Additionally, there are differences between Zenless Zone Zero's main servers: Americas, Asia, Europe, and Taiwan/Hong Kong/Macau. miHoYo does not support cross-region server transfers or account merging, so if you experience a connection failure, also check whether you have selected the wrong server.

When connecting to Zenless Zone Zero's servers, we need to focus on the validity of the connection, specifically whether data can be transmitted normally, especially over public networks, rather than being overly concerned about latency issues.
