Anybody else having issues with SoapUI 5.2.1 and NTLM?

So, it seems I can't use NTLM anymore inside of SoapUI.

What I've done so far:

1. Delete/Reinstall
2. Updated Java to 1.8 and verified via env variable, and start up says it's using java version 1.8.0_111
3. Tried with Postman (works great)
4. Tried in browser, no problems
5. Tried with WCFStorm.Rest and Windows Authentication and it works.
6. Made sure I'm running the app as "Run as Administrator"
7. Created a new REST Project to make sure things are clean.
8. Deleted the Authentication and reset.
9. Double checked that my account wasn't locked out.  (Ok, I'm reaching)

I'm specifically getting 401.1 errors if that'd help.

This was working at one point.

The IIS Server is 10.0, running on Windows 10 Enterprise.

if I start SoapUI from the command prompt, I see it starting up.

Looking at the IIS log files, it looks like it's not passing my credentials in to be authenticated.   I can see where I was using WcfStorm, and when I was just using Chrome.  Both passed credentials in.

So, anybody got any ideas of what I'm missing?

Thanks,

Nick
