This article addresses a common problem: the same free node may work occasionally for one person, but often fails to connect, drops out, or is inaccessible to some team members. The node itself may not be the problem; client versions, subscription updates, account environments, network egress, and how the node is shared can also play a role.
I. Common reasons free nodes fail to connect
Free nodes are generally intended for temporary testing or light use. Their stability can be affected by the number of active users, the status of the route, and protocol compatibility. These issues are more pronounced in a team, since everyone has a different network, device, and client.
- The node has expired or been replaced: Free nodes are updated frequently. An old link may still import, but fail to establish a connection.
- The subscription hasn’t been refreshed: Team members may be using a cached configuration and seeing an outdated node list.
- Different client cores: Clash, sing-box, V2RayN, and Shadowrocket don’t all support every protocol field in exactly the same way.
- Local network restrictions: Company Wi-Fi, campus networks, and carrier networks may block certain ports or UDP.
- Incorrect system time: TLS-based protocols are time-sensitive, and an incorrect computer clock can cause connection failures.
II. Why account environment stability affects team use
Here, “account environment” doesn’t mean an account on a self-hosted server. It refers to the devices, network egress, client settings, and usage habits of team members connecting through a node. Free nodes are generally not suitable for long-term, high-frequency use by multiple people. If several members connect to the same node at once, it may become congested, have connections reset, or become temporarily unavailable.
Also, without a shared configuration standard, teams often run into problems like these: some members have global proxy enabled while others use rule mode; some route DNS through the proxy while others have DNS leaks; some have imported the latest free nodes from this site while others are still using a configuration from several days ago. These differences make troubleshooting more complicated.
III. Team troubleshooting steps: check in order
- Have all members update their subscriptions, delete cached nodes, and import the configuration again.
- Standardize client versions. For example, use v2rayN or Clash Verge on Windows, and v2rayNG or sing-box on Android. Avoid outdated versions.
- Test with just one member, one device, and one node first to confirm whether the node itself is reachable.
- Switch networks to test: move from the company network to a mobile hotspot to check for local network restrictions.
- Disable global acceleration, game boosters, and any lingering system proxy settings to avoid conflicts between proxy apps.
- Check the system time, DNS settings, and routing mode. Start with rule mode; if a resource is inaccessible, briefly test global mode.
If the node works for one person but fails when several people use it at the same time, the instability is most likely due to the node’s capacity or shared use. In that case, spread usage across different free nodes instead of having everyone rely on the same route.
IV. How to reduce team connectivity issues
When a team is using free nodes temporarily, designate one member to maintain the subscription source and send update reminders. Everyone else should import the same link. Avoid repeatedly sharing individual node text in group chats, as it can lead to formatting errors or inconsistent versions.
Use free nodes as a backup or for testing—for research, temporary access, and client verification. For long meetings, large file syncs, or multiple people online at once, prepare several alternative routes. This site provides importable free nodes and client tutorials, but free resources are not guaranteed to remain available. When troubleshooting, first make sure the subscription is up to date.
Keep this rule of thumb in mind: if no nodes connect, the problem is probably with the client, network, or system environment; if only one node fails, it has probably stopped working; if one person can connect but the team experiences instability, focus on shared use, subscription consistency, and network egress.
