I'm working with an Azure function that has an inbound IP whitelist restriction.

My Nintex workflow attempts to call the Azure function, but is being blocked.

I would like to know the Azure region where Nintex O365 workflows reside.

I have already checked the FAQ https://community.nintex.com/t5/How-To-s/Nintex-Online-Services-IP-Addresses-to-Whitelist/ta-p/83587 , which state that Nintex workflows are hosted in Azure.

The recommedation on that brief post links to a site where ALL Microsoft  servers are listed.  If I have an Azure region that Nintex uses, I can at least limit my white list to under a hundred IP addresses.  Otherwise, manually entering hundreds of IP addresses appears to be the only option (madness).

Thanks in advance.
