You can try few troubleshooting steps
• Server Status: Verify that the destination server at the IP address 180.179.108.217 is powered on and the receiving service is active.
• Firewall/IPS: Check if a firewall or Intrusion Prevention System (IPS) is blocking the traffic between the appliance and the syslog server.
• Server Load: The destination server may be too busy to handle new connections, leading it to refuse them
• Connectivity Test: Use the telnet command via the CLI to test if the specific destination port is open and reachable
