Built on October 31st 2022 with the latest code. Not sure what to make out of this because with Monterey's networkQuality I see:

implying there is something wrong with the infrastructure (in theory it could be my adblocker but with adblocker paused this still happens).

Also https://mensura.cdn-apple.com/api/v1/gm/slurp just shows:

Thank you! I will attempt to recreate. Might be difficult because I am already running the Ventura beta (which appears to have gone golden a few days ago) but I will do my best!

Sorry it caused you trouble! Will

Hi Will,

not even sure it is goresponsiveness' fault. I am somewhat limited as my current macbook was dropped from receiving Ventura, so updating is not an easy option right now. I will test tomorrow from a different network to see whether this is repeatable.

[moeller0]

Mmmh, today it seems to work somewhat, both at a remote site as well as over a OpenVPN tunnel from the remote site to my home-network:

bash-3.2$ networkQuality -v

But note that after a successful networkQuality (apple) run the first attempt at the go code resulted in the following error:

Still on the second invocation it did work. Will repeat my test tonight with out the VPN from the problematic location.

[moeller0]

So I redid the test directly from within the problematic network and things just work.

However, it might be nice to not panic and give a more informative error message (apple's solution is IMHO better but also not perfect, but at least it allowed me to confirm that the website was not working as expected).
