v2rayNG Not Connecting? Team Guide to Checking Account and Environment Stability

This article addresses the issue where, when multiple people on a team use v2rayNG, “some can connect, some cannot, and the same node works well one moment and poorly the next.” It focuses on troubleshooting from four angles: accounts, subscriptions, mobile networks, and client settings, and is suitable for ordinary users to follow step by step.

1. First determine whether it is an individual issue or a team-wide issue

In a team setting, do not start by repeatedly reinstalling the app. First make a simple judgment: if only one phone fails to connect, it is most likely a problem with that device’s network, time, permissions, or configuration; if most members fail at the same time, the issue may be unstable nodes, subscriptions, or exit environments.

1. Have 2–3 members test separately using different networks, such as Wi-Fi, mobile data, and the company network.
2. Confirm that everyone imported the same subscription link and has clicked “Update Subscription” in the menu at the top right of v2rayNG.
3. Select the same node for testing, then switch to 1–2 other nodes for cross-checking.
4. Record the error messages, such as timeout, connection closed, and TLS handshake failed, to help identify the issue.

If everyone fails to connect only on the company Wi-Fi while mobile data works normally, first suspect company network restrictions; if it does not work on any network, then check the subscription and node status.

2. Common reasons why v2rayNG cannot connect

Subscription not updated is one of the most common causes. In teams, some people may go a long time without updating their subscription, and after old nodes become invalid they continue using them, leading to situations where others work normally while they fail. Open v2rayNG, tap the three-dot menu in the top right, select “Update Subscription,” and after it finishes, choose a node again and reconnect.

Inaccurate phone time can also affect TLS-based connections. Open system settings, change the date and time to “Set automatically,” then close and reopen v2rayNG. Some Android phones kill background apps as part of power-saving strategies, so it is recommended to allow v2rayNG to run in the background in the system battery management settings.

You should also check the local proxy status. After v2rayNG connects, a VPN icon will appear at the top; if there is no icon, it means the local VPN was not successfully established. In this case, disconnect first, then tap the round button in the lower right to reconnect, and make sure the system VPN permission prompt has been allowed.

3. What is the relationship between team accounts and environment stability?

When multiple people share the same configuration, stability is closely related to usage habits. Frequent simultaneous connections from many devices, different regions, and different network environments may cause certain nodes to become congested or trigger risk controls. Within the team, it is recommended to centrally manage subscription links and avoid casually forwarding them to unrelated devices.

• Use a unified subscription source: avoid members mixing expired QR codes, screenshot-based configurations, and old links.
• Test nodes in groups: do not have everyone crowd onto the same node for long periods.
• Keep a backup network: if the company network does not work, use mobile data to test whether the issue is a network restriction.
• Clean up old configurations regularly: if there are too many invalid nodes in v2rayNG, it is easy to choose the wrong one.

If you are using the free nodes provided by this site, it is also recommended to have a small number of members test availability first before rolling them out across the team. Do not treat free nodes as a long-term dedicated line.

4. Use this process to fix it quickly

1. Open v2rayNG, update the subscription, and confirm there are no errors.
2. Switch between 2–3 nodes for testing; do not focus on only one node.
3. Switch networks: if Wi-Fi does not work, try mobile data, and vice versa.
4. Check the phone time, VPN permissions, and power-saving restrictions.
5. Enable “Bypass LAN and mainland China addresses” in settings and try again.
6. If it still fails, delete the old subscription, then copy and import the subscription link again.

Finally, a reminder: if v2rayNG cannot connect, it does not necessarily mean the software is broken. In team use especially, you should distinguish among four types of problems: “node failure, subscription expiration, local device settings, and network restrictions.” Troubleshoot in the order above, and you can usually find the cause and restore the connection quickly.
