Build AI project from azure fails - Download DIFx

[aleksej-fp]

Hello

we are using advanced installer as VS project, building it from azure devops with VSBuild task.
This has worked till version ~22.x
Now we would like to prepare next release for our product and updated pipeline (now with AI v 23.4)
When I build updated project from VS or from my desktop AI - everything works.
But when I start my pipeline - I'm getting errors.

My task is:
- task: VSBuild@1
displayName: 'Build AI (exe)'
inputs:
solution: '**/MyProject.aiproj'

Output:
[ Release ]
Downloading the DIFx custom action DLL(s)
-536870888
Build finished because an error was encountered.

How can we fix this, to be able to build from azure devops?
If the download is blocked from our azure - what should I tell our IT department? Which url's should be whitelisted or any other actions performed?
