NetXMS Support Forum

I am currently having problems checking open ports with the Network Service Object.

OS: Ubuntu 16.04.5 LTS
NetXMS: 2.2.10
NxAgent: 2.2.10
CPU: 4 Cores
RAM: 4GB

I have installed the SubAgent PORTCHECK and it loads successfully. But every device the port check returns with the error "Unable to check service status due to agent or communication error".

I have checked,

• Agent is running
• Firewall
• NMAP on server returns open ports
• Reboot Server
• Restart NetXMS and NXAgent service

NxAgent Output
