I don't know enough about these tests or networking configuration to be a good judge of whether we should try to fix this or how, but want to discuss here if possible.
In particular:
Is this something we think we could fix or workaround in our code? The Test-Connection tests on macOS seem to have been flaky for some time.
Do we think there's some way we could improve the way the CI instance is configured to mitigate?
Otherwise, is there some other way we could perform test setup here that wouldn't hit this issue? Or possibly we could identify when we've hit this issue and handle it somehow?
From the test output:
Based on dotnet/runtime#29780 (comment), this seems to be a DNS resolution issue, and seems to be common on macOS.
