1. Install Required TLS Certificates:

   Ensure the TLS certificates for Unicode (TLS 1.2) and non-Unicode (TLS 1.3) are installed on your target server. These certificates are essential for secure communication.

2. Configure SSL/TLS Settings in Telegram Browser:

   • Open the Telegram browser and navigate to the settings.
   • Under "Protocol," change the connection protocol to MTProto.
   • For iOS, set the SSL/TLS version to https://https:// (Unicode connection).
   • For Android, set it to https://https:// (non-Unicode connection).

3. Set TLS Version in Settings:

   • In the "SSL/TLS" settings, specify the correct TLS version for each platform:
     • iOS: TLS version https://https://
     • Android: TLS version https://https://

4. Verify SSL/TLS Configuration:

   Test the proxy by connecting to a specific server in the Telegram browser. If successful, the connection should be secure and encrypted.

5. Check Certificate Installation:

   Ensure the MTProto certificate files are installed on the target server. These are necessary for the proxy to function correctly.

6. Test the Proxy:

   After setting up the proxy, connect to a server using the configured settings to verify its functionality and security.

7. Consider SSL/TLS Version Support:

   Confirm that MTProto supports multiple TLS versions (if applicable) to ensure compatibility with the chosen versions for iOS and Android.

By following these steps, you can successfully set up a Telegram MTProto proxy, enabling secure communication with specific servers over HTTPS.
