Then i tried -TransferEncoding "chunked" which tells me that i have to set the "SendChunked" property first. PowerShell limits remote connections to around MB for older versions. You can increase that limit by using Set-Item. But this may not fix the problem for very large files. BitsTransfer works for large files. Here is an example using Write-Progress.

You may copy the code below and paste it into your PowerShell session to test. The demonstration below shows the expected result after running the code above in PowerShell.
As you can see, the file download was successful. How about if the source requires authentication before allowing access? For example, the code below downloads a file from a private website where users must log in. If authentication is required, you should add a credential to the request using the -Credential parameter.
As you can see, the Get-Credential cmdlet prompted a PowerShell credential request. This time, using the credential with Invoke-WebRequest resulted in a successful download. A crucial thing to remember when using Invoke-WebRequest in Windows PowerShell is that, by default, this cmdlet uses the Internet Explorer engine to parse data.
