This article addresses the following: after obtaining a Clash subscription link, how to correctly import it into the client, update nodes, and troubleshoot the issue of “import successful but no internet access,” while also explaining why IP, DNS, and the browser environment can affect access results. It is suitable as a reference for ordinary users who are just starting to use clients such as Clash, Clash Verge, and Clash for Windows.
1. What You Need to Prepare Before Importing a Subscription
A Clash subscription is usually a link beginning with http or https that contains multiple proxy nodes and rule configurations. You can use your own subscription, or check the available free node information on this site. Before importing, it is recommended to confirm three things first: the subscription link has no extra spaces, the client version is relatively up to date, and the system time is correct. Many subscription update failures are not caused by node issues, but by an incompletely copied link or interception by the local network.
- Subscription link: Copy it in full; do not copy only part of the text.
- Clash client: Use the corresponding version for Windows, macOS, Android, and iOS.
- Basic network: First confirm that you can normally access domestic websites when the proxy is turned off.
2. How to Import a Subscription into Clash
The interface differs slightly across clients, but the process is basically the same. The following steps apply to most Clash-series clients:
- Open the Clash client and go to the “Profiles,” “Configurations,” or “Subscriptions” page.
- Click buttons such as “New,” “Add Subscription,” or “Import from URL.”
- Paste the subscription link into the URL input box. For the name, you can enter “freevpn” or a custom name.
- Click “Download,” “Update,” or “Save,” and wait for the configuration file to finish downloading.
- Return to the main interface, select the configuration file you just imported, and enable the system proxy.
- On the “Proxies” page, select a node. It is recommended to first test with automatic selection or a node with lower latency.
If there are no nodes after importing, first manually click update subscription once; if a YAML error appears, it usually means the subscription content is abnormal, the link has expired, or you copied webpage content after opening the link in a browser rather than the original subscription address.
3. How IP, DNS, and the Browser Environment Are Related
Many people think that after importing a subscription into Clash, as long as the switch is turned on, access will definitely work. In fact, access results are also affected by IP, DNS, and the browser environment. IP determines the exit location seen by the website. If a node is restricted, you may encounter CAPTCHAs, be unable to play content, or be denied access. DNS is responsible for resolving domain names into addresses. DNS pollution or cache errors can cause some websites to fail to open even when using the same node. The browser environment includes cache, cookies, language, time zone, WebRTC, and so on; some websites make a combined judgment on whether the login environment is abnormal.
When testing, it is recommended to first use an incognito window to access the target website; if a site cannot be opened, you can switch nodes, clear the browser cache, or switch between rule mode and global mode in Clash for comparison. For daily use, “rule mode” is generally recommended, and “global mode” should be used only briefly when troubleshooting.
4. Troubleshooting Import Failures and Connection Failures
- The subscription cannot be downloaded: check whether the link has expired, try switching networks, or open it in a browser to confirm whether it returns configuration content.
- The node has latency but webpages will not open: confirm that the system proxy is enabled and that the browser does not have a conflicting proxy extension installed.
- Only some websites cannot be opened: try switching nodes, clearing the DNS cache, or testing with another browser.
- All websites lose connectivity: turn off Clash to restore the network, then restart the client to avoid the proxy port being occupied.
- It does not work on mobile: check whether VPN permission has been granted, and confirm that no other VPN apps are enabled at the same time.
In general, the keys to importing a subscription into Clash are: “the subscription link is correct, the configuration has been enabled, the system proxy has been turned on, and the node is available.” When problems arise, do not keep reinstalling repeatedly; troubleshoot item by item according to the subscription, client, IP, DNS, and browser environment, and you can usually identify the cause.
