We have an application under test that has multi factor authentication enabled. Authentication is working as expected.
The issue is on one particular VM that was created for running tests. When we open the application from this VM, authentication times out (net::ERR_CONNECTION_TIMED_OUT). The VM cannot reach https://aadcdn.msftauth.net and https://aadcdn.msftauth.net.
Our network team has asked that a firewall request be submitted and the subnet values for aadcdn.msftauth.net and aadcdn.msftauth.net be included. May I know the subnet values, please?

See ranges here: Microsoft 365 URLs and IP address ranges
You can also get JSON formatted list.
