Clash for Windows Tutorial

Clash is a cross-platform proxy client written in Go. It supports Shadowsocks and V2Ray servers, though not ShadowsocksR. The core Clash client is available for macOS, FreeBSD, Linux, and Windows. “Clash for Windows” is a graphical user interface (GUI) for Clash on Windows.

This tutorial will demonstrate both core Clash from the command line on a Windows platform and the Clash for Windows GUI.

1. Create V2Ray Server

To follow along with this tutorial, you will need a V2Ray server. The examples in this tutorial use a V2Ray server that implements the WebSocket protocol. Tutorials elsewhere on this site explain in more detail how to create a V2Ray server. Therefore we will repeat here only the most essential steps to create a V2Ray server. This outline is for a server running CentOS 8 with an Nginx frontend. We assume that you start with a server that is up to date and with a firewall that is open for HTTP on port 80/tcp.

1.1. Install Nginx

Install and start Nginx:

yum install nginx

systemctl enable nginx

systemctl start nginx

1.2. Add Content

Add some sample content to the web server:

yum install wget zip unzip



cd sample-hexo-blog-master

cp -rf public/* /usr/share/nginx/html/

You can now test that your basic web server and its content appear as expected in a browser:

Sample Hexo blog

1.3. Install V2Ray

Install V2Ray:

cd ~



1.4. Configure V2Ray

Edit configuration file /etc/v2ray/config.json. Add error logging, make it listen on localhost only, and add specification of the WebSocket protocol and path /secret/. The results will look like this, except with your port and id:

  "log": {
    "loglevel": "warning",
    "access": "",
    "error": "/var/log/v2ray/error.log"
  "inbounds": [{
    "port": 38483,
    "listen": "",
    "protocol": "vmess",
    "settings": {
      "clients": [
          "id": "7d5af219-0ac5-491b-bfa8-68968d7a2774",
          "level": 1,
          "alterId": 64
    "streamSettings": {
      "network": "ws",
      "wsSettings": {
        "path": "/secret/"
  "outbounds": [{
    "protocol": "freedom",
    "settings": {}
    "protocol": "blackhole",
    "settings": {},
    "tag": "blocked"
  "routing": {
    "rules": [
        "type": "field",
        "ip": ["geoip:private"],
        "outboundTag": "blocked"

1.5. Reconfigure Nginx

Edit /etc/nginx/nginx.conf. Set the server name. For example, if your hostname is


Create /etc/nginx/default.d/v2ray.conf. Specify a location block to send requests for the /secret/ directory to V2Ray on its listening port. With our example of port 38483:

location /secret/ {
        proxy_redirect off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;

Set the SELinux boolean to allow Nginx to make network connections:

setsebool -P httpd_can_network_connect 1

1.6. Restart Services

Restart V2Ray and Nginx with their new configurations:

systemctl start v2ray

systemctl restart nginx

2. Create Clash Configuration File

Now that you have a V2Ray server, you can proceed to connect to it from your Windows client using core Clash from the command line.

2.1. Format

Clash is driven by a configuration file in “YAML Ain’t Markup Language” (YAML) format. The documentation for the configuration file format is at

2.2. Example

Here is an example of a simple Clash configuration file. This one is designed to match up with the V2Ray configuration give above.

port: 7890
socks-port: 7891
allow-lan: false
mode: Rule
log-level: info
  - name: "San Francisco"
    type: vmess
    port: 80
    uuid: 7d5af219-0ac5-491b-bfa8-68968d7a2774
    alterId: 64
    cipher: auto
    network: ws
    ws-path: /secret/
Proxy Group:
  - name: Proxy
    type: select
      - "San Francisco"
  - FINAL,Proxy

2.3. Create Configuration File

The default configuration directory for Clash is %HOMEPATH%\.config\clash.

On your client PC, open a Windows Command Prompt (Windows+r, type cmd, and click OK).

Make the required directory:

mkdir .config

cd .config

mkdir clash

Close the Command Prompt window.

In a text editor such as Notepad or Notepad++, start a new file for your Clash configuration. Add content to the configuration file, based on the template above. At a minimum, you will likely want to replace:

Save the file in your %HOMEPATH%\.config\clash directory with the name config.yaml. Close the text editor.

3. Install and Run Command-Line Clash

3.1. Download Clash

Binaries for macOS, FreeBSD, Linux, and Windows are available for download from

Download the most recent file for Windows. In our example, we will use

Unzip your downloaded zip file. This creates a folder, Downloads\clash-windows-amd64-v0.17.1.

3.2. Run Clash

Open a Command Prompt window by typing Windows+r, entering cmd, and clicking OK.

Change into the unzipped directory. Continuing our example:

cd Downloads\clash-windows-amd64-v0.17.1

Issue the command:


The first time you run Clash, it cannot find the country database, Country.mmdb. It therefore downloads it. It then listens on ports 9090 (for the API), 7891 (for the SOCKS proxy), and 7890 (for the HTTP proxy).

Leave the Command Prompt window open, with Clash running in it.

3.3. Configure Browser

Now configure your browser to use the SOCKS proxy listening on localhost port 7891:

3.4. Test Browser

Test your browser by visiting You should see your server IP address, not your client IP address.

3.5. Stop Test

When you are done, go back to the Command Prompt window where Clash is running. Do Ctrl+c to stop Clash. Close the Command Prompt window.

Set your browser back to its direct, non-proxied settings.

3.6. Clean Up

To prepare for the next test:

  1. Copy config.yaml from your .config\clash folder into your Downloads folder
  2. Rename Downloads\config.yaml to Downloads\profile.yml
  3. Delete your .config\clash folder

4. Install and Run Clash for Windows

Now we will switch from using the command-line interface (CLI) to the GUI.

If you have followed the steps above, you should start this step with a Downloads\profile.yml file ready for the GUI.

4.1. Download Installer

Visit Github at

Clash for Windows releases

Download the most recent installer. At the time of writing, this is named Clash.for.Windows.Setup.0.8.11.exe.

4.2. Install Clash for Windows

Launch Clash.for.Windows.Setup.0.8.11.exe.

Launch installer

Windows Defender SmartScreen may pop up. If this happens, click More info.

SmartScreen More info

Select Run anyway.

SmartScreen Run anyway

During installation, select who will run Clash for Windows: either anyone or only you. The “Anyone” option requires Administrator rights on the PC.

Anyone option

Click Yes to allow the installer to make changes to your computer.

Allow changes

Accept the default installation location.

Installation folder

At the end of installation, leave the box checked to start Clash for Windows.

Start Clash for Windows

4.3. Run Clash for Windows

Locate the Clash for Windows icon in the system tray. It looks like a dark blue cat. Right-click on the icon, and select the option to bring up the Dashboard. The first time you bring up the Dashboard, you may get an error message. If this happens, just quit and restart Clash for Windows.

Now you will see the initial Dashboard:

Start Clash for Windows dashboard

4.4. Configure Clash for Windows

On the General tab, toggle System Proxy to the ON position. This saves having to manually configure each browser to use Clash.

System Proxy

Go to the Profiles tab. The initial configuration file is .config\clash\config.yml (note that the file extension ends in yml, not yaml).

Initial config.yml profile

You can either download a configuration file from an online URL, or you can manually import a configuration file you have already downloaded. The online URL method is intended for service providers. For this tutorial, we will import a local configuration file.

In real life, the imported file might be a partial profile containing only Proxy, Proxy Group, and Rule. For the purposes of this introduction, we will simply reuse the configuration file we used for the CLI version of Clash.

Drag and drop your Downloads\profile.yml file from your Downloads folder into the Clash for Windows dashboard. Select it, and it will be highlighted:

Imported profile

On the Proxies tab, select your Proxy:

Proxy selected

4.5. Test Clash for Windows

Open a browser.

Start playing a video from YouTube. Leave the video playing, and go to the Connections tab. You will see your active connections:


4.6. Stop Test

This is the end of this tutorial.

Stop the YouTube. Locate the Clash for Windows icon in the system tray, right-click on it, and select Quit.

5. Troubleshoot Issues

If you encounter any problems when using Clash for Windows, try to troubleshoot yourself first.

Firstly, double-check that your client configuration, your server V2Ray configuration, and your server Nginx configuration all match up with each other.

Check the latest logs on the client under the configuration folder, %HOMEPATH%\.config\clash\logs.

If you have access to the V2Ray server, you can look in /var/log/v2ray/error.log and /var/log/nginx/error.log.

Use a search engine to see if anyone else has reported the same error before.
