Hi all,
I launched the Azure ATP sizing tool in my client environment but I get a "Tool failed to start working with this machine" on 3 DCs. Those DCs are recent and hosted in Azure.
I can't find any prerequisites within the Azure ATP Sizing Tool documentation, do you know what could be wrong?
Thank you

Probably one or more ports are blocked.
See the description paragraph at

for which ports are used and how.
