This article explains how to configure a WS TLS node and why it might not connect after import. Follow the steps in order: prepare the client, enter the settings, and verify the connection. It also explains how IP addresses, DNS, and browser settings affect connectivity. This guide applies to VLESS or VMess nodes provided by a service provider; it does not cover setting up your own server.
1. Check that you have all the node details
WS is a WebSocket transport method, and TLS encrypts the connection; neither is a standalone node protocol. Before configuring the node, check whether it uses VLESS or VMess, then gather the server address, port, UUID, WS path, Host, and TLS SNI. If the VLESS node has additional encryption parameters, enter them as specified by the provider.
The server address, WS Host, and SNI are not necessarily the same: the address determines the connection destination, Host is used for the WebSocket request, and SNI is used during the TLS handshake and certificate verification. Don’t change them all to the same IP just because they look similar.
2. Install the client and import the node
- Install a client that supports the relevant protocol, WS, and TLS from the project’s official website or release page. Examples include v2rayN for Windows and v2rayNG for Android. Menu names may vary between versions.
- Copy the complete vless:// or vmess:// link, then select “Import from clipboard” in the client. If you have a subscription URL, add it in the subscription manager and update it rather than pasting it into the server address field.
- After importing, open the node’s edit page and verify the protocol, address, port, and UUID. Set the transport to ws or WebSocket, and enable TLS as specified in the node details.
- Check the WS path, keeping its leading slash and any existing query parameters. Enter the Host and SNI as provided. The port is not necessarily 443, so don’t change it based on guesswork.
- Save and select the node, enable the client’s system proxy, and test the connection by visiting a working HTTPS website. On mobile, if the client needs to create a VPN connection, make sure it has system permission.
Import the complete link when possible to avoid manual entry errors. With Clash or sing-box, import a configuration or subscription that is compatible with the client; don’t assume they can all directly recognize a single share link. You can also practice importing with free nodes provided by this site, but confirm availability by testing them.
3. What IP, DNS, and browser settings affect
If the server address is a domain name, DNS usually needs to resolve it before a connection can be established. If you see a “domain resolution failed” error, first check your local network and the client’s DNS settings; don’t switch to an unfamiliar IP you found online. Even if you use an IP as the connection address, TLS may still require the original domain as the SNI.
A browser’s Secure DNS setting or proxy extension may behave differently from the system proxy or client rules. If the client shows as connected but webpages won’t load, temporarily disable other proxy extensions and test another browser. If needed, compare the results with Secure DNS turned on and off, then restore the appropriate setting. Incognito mode cannot fix incorrect node parameters.
4. Troubleshoot connection failures in this order
First, update the subscription and check that the node is still active. Then verify the system time, server address, and port. If the log reports a certificate error, check the SNI and device time. Don’t routinely disable certificate verification as a workaround. If it reports a WebSocket handshake failure, focus on the path, Host, and transport type. If the connection times out, check your local network and whether the destination is reachable, then try a different network for comparison.
Finally, confirm that the system proxy is working and that the rules aren’t incorrectly routing the destination website directly. Change one setting at a time and record the result; this makes it easier to pinpoint the issue than changing DNS, SNI, and the path all at once. Before sharing logs to ask for help, hide your UUID, subscription URL, and any other credentials.
