Hi Nguyen.
I am also Regional Technical Support Manager for Ross Video based in Melbourne, Australia.
The most probable explanation to your problem is that the IPS and your computer, where you have installed Phoenix, are on a different network subnets.
Please check the IP addresses and let me know.
It is easy done for the PC. For the IPS, click on the IPS in Phoenix IPS Explorer and have look at the Properties.
Please let me know if you need more detailed explanations.

Best regards
Jacek
