I have an IIS site with NTLM and sitespeed.io, run via Docker, seems to be unable to get past the NTLM Part.
I'm very new to sitespeed.io but have searched their documentation and found nothing to say it does, or does not, specifically support NTLM.
The script I have been running on a Windows 10 machine is:
docker run --rm -v "%cd%":/sitespeed.io sitespeedio/sitespeed.io http://intranet.company.com/Pages/default.aspx#/
