Getting started after deploying 3X-UI¶

After payment of the order, a notification of the server's readiness for operation will be sent to the e-mail address specified during registration. It will contain the IP address of the VPS, as well as the login and password for connection. Clients of our company manage the equipment in the server control panel and API - Invapi.

Here you can also find the credentials, which can be found either in the Info >> Tags tab of the server control panel or in the email sent to you:

• Link to access the 3X-UI webpanel: in the webpanel tag. The exact link of the form https://{Server_ID_from_Invapi}.hostkey.in:XXXXX comes in the email sent when the server is handed over;
• Login: root;
• Password: Sent to your email address after the server is ready for use following software deployment.

Set up a New Connection¶

1. After logging into the 3X-UI panel, go to the Inbounds tab and click on the Add Inbound button:

   

2. Fill in the following fields in the opened menu:

   • Remark - name the connection using the protocol type (e.g. VLESS) or client group type.This name will be displayed in the list of incoming connections;
   • Protocol - protocol selection is set to vless by default, but it can bechanged and configured manually if desired;
   • Listen IP - if you leave this field empty, the server will listen on all IP addresses;
   • Port - specify port 443.

   Note

   The fields Total Flow (GB) and Expire Date are optional.

   

3. Select the REALITY tab located under Security at the bottom of the window.

   

4. Navigate to the client settings and complete the necessary fields in the Client section.

   • Email - client ID, must be unique. If entering an email, it must also be unique for each protocol. If you have a user, keep the existing one or create a new user by clicking the icon next to the email field. If there are multiple users, set a readable identifier such as [email protected].
   • ID - unique identifier for the incoming connection. The ID must be 32 characters long and can only contain numbers and lowercase letters of the Latin alphabet. It can be generated automatically by clicking the icon in front of the key input field.
   • Flow - the value is set to xtls-rprx-vision.

   

5. Navigate to the REALITY setting and select chrome in the uTLS field, or choose another option from the list.

6. Enter the domain to mask in the Dest and SNI fields. The default option is yahoo.com.

   Attention

   Consider selecting a different domain from the proposed options and replacing the default one in the corresponding fields:

   • Dest: www.microsoft.com:443 and SNI: www.microsoft.com
   • Dest: dl.google.com:443 and SNI: dl.google.com

7. In ShortIds click on the icon . This action will generate a random ID.

8. Click the Get New Cert button to generate new keys for Private Key and Public Key.

   

9. After entering the data, click the Create button.

If configured correctly, you will have an entry with the protocol.

Connections for other protocols can be configured in the same manner.
