Observing very different behaviour from two Monitoring Points (MPs).
Single-ended paths to Teams are working on MacOS MPs, but not Windows MPs even though Teams is pingable from all of them. The same issue is seen on paths to ServiceNow.
For example, two MPs are in the same rack and connected to the same network, yet they exhibit this issue (MacOS can reach Teams and other services, Windows cannot)
