Any command to fly.io causes connection error on windows 11

Running e.g.
iwr https://fly.io/install.ps1 -useb | iex

causes:
iwr : The underlying connection was closed: An unexpected error occurred on a send.
At line:1 char:1

  • iwr https://fly.io/install.ps1 -useb | iex
  •   + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-WebRequest], WebException
      + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand
    
    

This is on a clean windows 11 machine.

I installed it manually - and then got a similar error when running login:

flyctl : Error Post “https://api.fly.io/api/v1/cli_sessions”: read tcp

It must be some issue with connecting… but I’m not sure what could be causing it - I’ve got internet access.

Same Issue, did you find any way out?
