How To Setup v2ray Websocket(WS)+TLS+CDN on a VPS (updated x-ui)


Good news! Vless xtls tutorial is ready. Click here to read. 


What is v2ray?

V2ray or vmess protocol to be precise, is a sophisticated version of the famous Shadowsocks. At the core, v2ray is also based on SOCKS5 proxy. Normally, proxies lack encryption, and that’s what differentiates a VPN and a proxy. Shadowsocks is SOCKS5 proxy with an encryption, and vmess is the next gen Shadowsocks. 

The previous articles were about simple v2ray with tcp protocol, and that was enough for that time. But recently my v2ray tcp servers got blocked. So I believe it is time to move to more complicated configurations of v2ray. 

This method is called v2ray+websocket+tls+cdn (sometimes nginx is also added, if you  prefer to add a website). As to my understanding, this method hides your VPS IP address behind an IP address from a major CDN provider like Cloudflare, and most ISPs do not block those IP addresses.

There are several scripts for this method, including a good one from 233boy. But, in this article, I am using the easiest one from sprov065 called v2-ui, which also includes an easy v2ray multi user management panel.

Update 2021:

As the developer of v2-ui, changed the v2ray panel to x-ui, which is based on xray core, this tutorial is updated accordingly. The new panel has some design and functionality changes. Most of the installation is same as before. The x-ui panel is only in Chinese right now, but you can use google translate to understand it.

Note: I will update screenshots later.


Choosing a VPS

You should:
  • Before making payment ping an IP address of the VPS provider
  • Prefer hourly billing VPS services
  • Prefer less popular VPS services
  • Check for ratings and user reviews
  • Prefer KVM virtualization
  • Use a VPN when using Putty or an alternative SSH programme, to prevent IP address blocking

I can suggest these VPS services:

  1. Vultr – hourly billing – starting from $3.5 per month – (get a $100 bonus)
  2. DigitalOcean – hourly billing – starting from $5 per month – (get a $100 bonus)
  3. RackNerd – monthly billing – starting from $2 per month (annual subscription) –
  4. Contabo – monthly billing – starting from € 3.99 per month  –
  5. CloudCone – hourly billing – starting from $4.2 per month –

Setting up v2ray ws+tls+cdn 

Good news! Vless xtls tutorial is ready. Click here to read. 

Thanks to the one-command script by sprov065, you can install v2ray easily, even if you are not familiar with Linux commands. 

You need to have at least Ubuntu 16, Debian 8 or CentOS 7. 

This guide will be for Debian and Ubuntu.

The setup consists of two parts. First, the v2ray script installation, and the second is getting a free SSL certificate from Let’s Encrypt for TLS, and enabling CDN from Cloudflare. The second part is only needed if you wish to use tls and cdn.

Part one – install the script

1. First make updates and upgrades, and install curl

sudo apt-get update -y 
sudo apt-get upgrade -y
sudo apt install curl -y

2. Run the x-ui script

bash <(curl -Ls

a) First question asks whether you agree. Press y.


b)Second one asks for account username. Write whatever you want as when you log in.


c)Third one asks for account password. 


d) The last question asks you to write a port number for your user panel.


And that is it for the installation part.

x-ui installed 

Part two – get the SSL Certificates

You will need:

  • A domain name
  • A Cloudflare account
  • Point your nameservers to Cloudflare
  • Point your VPS IP to your domain name

To get an SSL certificate, you need a domain name (, preferably a paid one from providers like namecheap or porkbun, and a Cloudflare account. Both Porkbun and Namecheap have free Whois Guard. When it comes to pricing, Porkbun has an upper hand, you can find domain names for under $3 per year. Please do check the renewal prices before purchasing a domain.

 1. Nameservers configuration

When adding your domain name to your Cloudflare account, Cloudflare will ask you to redirect your nameservers. It will be something like this:

You need to copy those from Cloudflare to your domain name registrar (ex: On Namecheap you can find it on Domain List > Manage > Nameservers. Change the DNS to Custom DNS and add Cloudflare nameservers. After a while, Cloudflare will inform you that the setup is done.,

2. Connecting your domain name to the VPS IP address
On Cloudflare,
  1. Go to DNS Management
  2. Press “Add Record”
  3. Type your sub-domain name or domain name to “Name”  (ex: write test for or @ for
  4. Write your VPS IP to “IPv4 address”.
  5. Make sure the color of “Proxy status” is orange and says DNS Only.

Note: If you keep DNS only status after SSL configuration mentioned below, you will get v2ray+ws+tls. If you change it to Proxied, you will get v2ray+ws+tls+cdn.

And lastly change SSL/TLS mode to Full or Full (strict).
3. Getting SSL Certificate

Now SSH to your VPS using Putty. 

  1. Install certbot.
sudo apt install software-properties-common
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get install certbot -y

 2. Use certbot to get SSL Certificate. Use your own email address and domain name.

sudo certbot certonly --standalone --preferred-challenges http --agree-tos --email your-email-address -d 

3. If you get a note like “Successfully received certificate”, it means that now you have SSL certificate for your  domain/sub-domain.

In the text you will find destinations of your certificate file and key file. Copy them, as you will need  them on web panel. It will be something like this:



If you face errors and cannot get the certificate, please make sure that your firewall is listening to ports 80 and 443, you have pointed your VPS IP address to the domain name and the Cloudflare CDN is off.

4. Last, the SSL certificate expires in 90 days, to make sure to renew it before expiration. Here is a manual renewal command.

certbot renew --force-renewal
LetsEncrypt_SSL Managing  v2ray

Adding a user

You can go to x-ui web panel typing your IP address and the port that you chose during installation (12345 in my case) on a browser. You can login using your username and password.


To add a user, you need to go to “accounts”, press add button and fill in the blanks according to  your preferences.

  • Remark – here you can write anything you want
  • Protocol – vmess
  • Listening IP, Port, ID (UUID) and Alter ID generated automatically. You can change them manually, as well. It is advised to use port 443. 
  • Transport – ws (websocket)
  • Path – you can leave it the way it is or add anything you want
  • Turn on TLS
  • Domain – write your domain name or sub-domain name
  • You can choose certificate file path and copy the file paths, or copy the certificate and key directly to certificate file content
  • Copy and paste certificate and key file paths, respectively
  • Press “Add”

And that is it. You can add, edit, delete users within seconds, and check bandwidth usage using x-ui web-panel. 

You are not only limited to v2ray ws tls cdn with this web panel, you can configure and test various combinations of v2ray.

I would like to thank vaxilu and other developers for this easy v2ray multi-user management panel.  



BBR script

If you think your v2ray has slow speed, or have an older Linux version on your VPS, you can use bbr script by teddysun, to install google bbr.

wget -N --no-check-certificate && chmod +x && bash

    1. Normally, if your VPS IP is a US IP address, then the website you are visiting will think that you are browsing from the US. You can try using v2ray without CDN.

  1. hi
    If possible, give an example for the command below
    2. Use certbot to get SSL Certificate. Use your own email address and domain name.

    sudo certbot certonly –standalone –preferred-challenges http –agree-tos –email your-email-address -d

  2. Thanks for the tutorial!!

    I got this error on the main panel and the server is no longer working. Any thoughts on how to fix this?

    1. hi,

      It looks like TLS certificate issue, you could try to re-issue TLS/SSL certificate. If that does not help you could re-install the script.

  3. Hi,
    This command did not run for me and it gave me error:

    sudo add-apt-repository ppa:certbot/certbot

    But the rest of the commands were successful and I got to the ui and created a user but it does not connect. Is it because of that line failing? I used unbuntu 22.04
    Please assist.

  4. Hi,
    The script to setup UI, gets stopped at this line:

    Connecting to (|2606:50c0:8000::154|:443…

    What can I do?

  5. Hi,
    I was able to make it work but it is very slow connection up to 5 to 10 seconds.
    My ping to server is 100ms .
    I tried the BBR script but it didn’t help the speed.

    Is there anything we can do to fix the speed problem?

    Thank you.
