Powershell Invoke-RestMethod “Unable to connect to the remote server”

i write simple powershell script post json string server. have strange issue when execute script.

1. the server inside our intranet, firewall disable intranet server. server uses http , no authentication required.
   

2. i tried execute script in different places:

   • powershell window in own computer (windows 7, powershell 5)
   • powershell ise in computer
   • start powershell.exe in command prompt in own computer

   • start powershell.exe in third party command prompt application in own computer

   • powershell window in citrix seesion (windows 10, powershell 5)

   • start powershell.exe in command prompt in citrix seesion

i checked of 6 places have executionpolicy "remotesigned",

but, can execute script in last 3 places,

in first 3 place, error

invoke-restmethod : unable connect remote server @ f:\temp\test.ps1:46 char:9 + $resp = invoke-restmethod -method post -body $result ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + categoryinfo : notspecified: (:) [invoke-restmethod], webexception + fullyqualifiederrorid : system.net.webexception,microsoft.powershell.com mands.invokerestmethodcommand

a few more information:

• i tried invoke-webrequest, got same error message.
• if have fiddler open, can execute script post in first 3 places.
• in command prompt, can post server using curl.exe. if enter powershell mode in same console, couldn't using invoke-restmethod same server

any idea why happen, should information?
