Call Web Service located on site with Negotiate provider

Hello! I'm trying to use Call web service action in my worklow to request data from web service, which is located on IIS web site with the following list of auth providers:

 

And I'm always getting 401 unauthorized error when just trying to get the list of available methods:

   

I remember, that i faced this issue before, with different server\site\webservice and fixed that by leaving only NTLM in list of providers. But now I can't do that, since we need Negotiate (and Kerberos) by design )

 

As I understand, it just can't negotiate Kerberos and fallback to NLTM, simply giving me "Unauthorized".

 

Any ideas are welcome!
