This article explains how to configure a WS TLS node and why it may fail to connect after import. Follow the steps in order: prepare the client, enter the settings, and test the connection. It also explains how IPs, DNS, and the browser environment each affect the process. This applies to VLESS, VMess, and other nodes that support WebSocket and TLS; it does not cover server setup.
1. Prepare the client and complete node details
Install the version that matches your device from the client’s official release channel—for example, v2rayN on Windows or v2rayNG on Android. If you use a client such as Clash or sing-box, make sure the subscription format is compatible with it. You cannot use arbitrary configuration files interchangeably.
Whenever possible, use the node link, QR code, or subscription URL provided by your provider. Before configuring a node manually, gather the server address, port, protocol, UUID, transport, WS path, Host, and TLS server name. WS TLS is a combination of transport and encryption, not a standalone protocol, so first select the correct protocol, such as VLESS or VMess.
2. Import the node or enter its settings in order
- Copy the node link and choose “Import from clipboard” in the client. If you have a subscription URL, add the subscription and update it. Do not enter the subscription URL in the server address field.
- To add a node manually, select the appropriate protocol and enter the server address, port, and authentication details. Use the port specified by your provider; do not assume that every node uses port 443.
- Set the transport to WebSocket, sometimes shown as “ws.” Copy the full path exactly, preserving the leading slash, capitalization, and query parameters. Do not change it to “/” on your own.
- Enter the domain specified by your provider in the WS Host field. Enable TLS and enter the SNI specified for the node. The client may also call this the “server name.”
- Save and select the node. Run a latency test first, then enable the system proxy and visit a webpage. On phones, you may need to allow the client to establish a VPN connection.
The server address, WS Host, and TLS SNI serve different purposes: the address determines the connection target, Host is used for the WebSocket request, and SNI is used during the TLS handshake and certificate validation. They may be the same or different; do not substitute one for another just because they are domains.
3. What IP, DNS, and the browser affect
If the server address is a domain, the client needs DNS to resolve it to an IP address. If you enter an IP directly, the Host and SNI may still need to be set correctly. Do not replace a domain with its resolved IP just to “avoid DNS lookup”—the service may rely on domain-based routing, and IP addresses can change.
DNS resolution failures may appear as an inability to find the server. For TLS errors, check the SNI, certificate validity, and device time. Do not treat disabling certificate verification as a standard fix; it weakens connection security.
Browser fingerprint, language, and time zone settings generally do not determine whether a WS TLS handshake succeeds. If the client connects but the browser cannot open webpages, first check whether the system proxy is working, then temporarily disable any conflicting proxy extensions. Secure DNS in the browser may affect website lookups, but it does not necessarily handle DNS lookups for the node domain made by the client.
4. Diagnose connection failures based on the error
- Connection timeout: Check the address and port, confirm the node is still active, then test on another network.
- Handshake failure or certificate error: Check that TLS is enabled, verify the SNI, and confirm the system time.
- 400, 403, 404, or similar response: Check the WS path and Host first; the server may also have restrictions.
- Latency test succeeds but webpages fail: Check the proxy mode, routing rules, and DNS. A successful test does not mean every website will be accessible.
When using free nodes from sources such as this site, check the last updated time and supported clients first. If a node is no longer working, try another available configuration. Subscription links may contain access credentials, so hide the link and UUID before sharing troubleshooting screenshots.
