Having trouble uploading large files with Invoke-RestMethod - powershell

Question

I am trying to use the Hashicorp Atlas restful api to upload box files into but I am running into problems when uploading large files.
I am currently using the following command which works with small files like 100mb but most box files are well over 4GB where I start to see the problem:
$Filename = "c:\box\mybox.box"
$uploadpath = "https://archivist.hashicorp.com/v1/object/example"
$Timeout = 86400 #24 hours
Invoke-RestMethod -Uri $uploadPath -Method Put -InFile $Filename -TimeoutSec $Timeout -ContentType "multipart/form-data"
The error:
Invoke-RestMethod : The underlying connection was closed: An unexpected error occurred on a send.
At C:\Program Files\WindowsPowerShell\Modules\atlasbox\1.1.15\AtlasBox.psm1:642 char:5
+ Invoke-RestMethod -Uri $uploadPath -Method Put -InFile $Filename ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException
+ FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand
If I use CURL command as per the documentation it works fine.
curl -X PUT --upload-file /path/to/my.box https://archivist.hashicorp.com/v1/object/example
Any idea how to make Invoke-RestMethod behave the same way curl does?
I can't take a dependency on curl because not all systems I run this on will have WSL installed and no curl.

Looks like it might be getting weird on the SSL cert? I would try some of the recommendations here to start with, definitely an oddity specific to those cmdlets though:
