Can you ping vCenter server?

[grglzrv]

Nope, I got timeout

Request timeout for icmp_seq 0 .. 1 .. 2 etc

but I can open it via web browser without any problem

[bedenko]

and URL in web browser is the same as the address that is being pinged?

Cause it looks like DNS problem.

[grglzrv]

Yeah the same domain, I use domain name, i am testing it with public subdomain for example: esxi.example.com, also I use reverse proxy to forward the traffic to the internal VMware IP and port. is it may be the cause?

[bedenko]

probably. Try to execute the script from internal network (behind proxy)
