Complete Onion Chat Server Setup

The SimpleX chat server is already installed on a Linux host and the Tor onion service is live, yet the setup is still only halfway there. I need someone to step in, smooth out the remaining configuration, and make sure the service is solid, secure, and ready for everyday use.

What is in place
• Linux host running the SimpleX server code (basic installation)
• Tor is installed and the .onion address resolves

What still needs attention
• Finish compiling or upgrading to the latest SimpleX release (if required)
• Review and complete all server configuration files
• Confirm traffic flows only through the onion endpoint and the correct ports are open
• Create or polish a systemd service so the server auto-starts on reboot
• Run connectivity tests from a SimpleX client to ensure chats work end-to-end

Deliverables
1. A fully functioning SimpleX chat server reachable at the existing .onion URL
2. Clean, commented configuration files stored on the server
3. A brief README that lists the main commands for starting, stopping, and updating the service

When you respond, please highlight your previous experience with Linux servers, Tor onion services, or SimpleX (or similar chat platforms). I am ready to move quickly once the right person is on board.
