Script works in PowerGUI, not in ISE or from powershell.exe

Question

Hi,
I am trying to integrate with the Manage Engine Password Manager PRO Rest API.. I have some code working on my desktop where I currently use PowerGUI this was all seemingly working correctly.. I have then gone to execute the code from a window on the same
machine and it doesn't work. I have also tried it in ISE with the same error...
Now the odd thing is if I choose "run in external window" from powergui and then run the script it works fine..
What the hell is going on for this window and the powergui console to be different?
the error I am getting is:
Invoke-RestMethod : The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
which I would expect if I was running the code on a machine where the Auth Code isn't registered, as you link an API user to a hostname..
code:
$inputData = @"
INPUT_DATA={
"operation":{
"Details":{
"RESOURCENAME":"PLdwdwd999",
"ACCOUNTNAME":"fefefeL999-Wallis-SQLSV",
"RESOURCETYPE":"Windows",
"PASSWORD":"fefefefef",
"NOTES":"fefefwerhthrtbrbr",
"RESOURCEURL":"http://192.168.0.1",
$uri = "https://xxxwintspmp001:7272/restapi/json/v1/resources?AUTHTOKEN=a111111-1111-411B95E-0B6DFE643CE3"
$resp = Invoke-RestMethod -uri $uri -Body $InputData -Method Post
System.Threading.Thread]::CurrentThread.GetApartmentState()
returns STA in both windows too..
please help, I'm now stumped.
Regards
David

If I had known I was getting certificate errors I wouldn't have posted this here would I?
Nor did powershell come up with a message to tell me, it was only when you mentioned proxies that I went down that avenue of investigation...
Sorry. I missed it in all of the description. This is why it is so important to copy and paste the complete error message and not just portion:
You posted above: "Could not establish trust relationship for the SSL/TLS secure channel"
The SSL/TLS should have clued me.  That means the cert was rejected.  To accept bad certs you need to do as you did and return $true on the callback.
I am surprised that PowerGui does that.  Are you sure the code is identical or did you option GUI to accept bad certs?
The dummied callback will effect every connection in you session until PowerShell is closed.
¯\_(ツ)_/¯
