Hello Hongchuong
it really looks like a blocked network communication. You write no firewall is blocking it but let's get into more details. The connection needs to be established from the Hyper-V host (10.132.2.200) to the ESXi host (10.132.2.192) on port 902, as in log lines:

An easy way to try the connectivity is telnet from the Hyper-V host to the ESX host on port 902
I see you have also tried again to destination 10.132.2.191 with the same error. It is possible the Hyper-V firewall is blocking.
