Invoke-WebRequest Error: An unexpected error occurred on a send

Question

When I run the following command using cURL.exe to upload a file, I have no issues:

Curl.exe -X POST -H "X-API-TOKEN: token here" -F file=@"E:\program files\curl\filetoupload.csv" 
https://url.com/files

I need to run it from a script so I thought I would use PowerShell's Invoke-WebRequest.When I run the following code I get

Invoke-WebRequest : The underlying connection was closed: An unexpected error occurred on a send.
 At E:\Scripts\Celero\qualtrics.ps1:8 char:13
+ $response = Invoke-WebRequest -Headers $headers -Method Post -OutFile ...
+             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke- 
WebRequest], WebException
+ FullyQualifiedErrorId : 
WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand"

 $filepath = "e:\program files\curl\filetoupload.csv"
 $headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
 $headers.Add("X-API-TOKEN", "token here")
 $urlAPI = "https://url.com/files"

 $response = Invoke-WebRequest -Headers $headers -Method 'Post' -OutFile $filepath -URI $urlAPI

I have tried adding

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12,[Net.SecurityProtocolType]::Tls11

and

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls -bor [Net.SecurityProtocolType]::Tls11 -bor [Net.SecurityProtocolType]::Tls12

With no luck. Any ideas?

UPDATE I ended up doing this in PowerShell:

param ($curlExe, $filepath, $headers,$qualtricsAPI,$jobfile)

try{
  Copy-Item $jobfile -Destination $filepath
$upload = & $curlExe -X POST -H $headers -s -o -w "%{http_code}" -F file=@$filepath $qualtricsAPI
if ($upload -match "200 - OK"){
    Write-Host "Upload successful."
    Write-Host "Response: "$upload
    Remove-Item $filepath
    Write-Host "File removed from $($filepath)."
    exit 0
}else{
    Write-Host "Upload not successful"
    Write-Host "Response: "$upload
    exit 2
}
}catch{
    "Exception Message: $($_.Exception.Message)"
    exit 1
}

I've tested it with our automation tool for file transfers and was successful. I was spinning my wheels on Invoke-WebRequest cmdlet.
