URLs marked as failure but no errors displayed

[NeilHanlon]

For some reason, reddit.com urls began acting strangely in our usage of urlchecker-action.

See an example run here -- these urls report no issues above (despite verbose=True), and this makes it impossible to debug why the checks are failing.

Any help/suggestions on what may be happening would be greatly appreciated. We're running urlchecker-action@master.

Is this new / were they OK before? Could it be ephemeral?

It's new, as in it has been occurring for several weeks, so not "new" as in ephemeral.

Does it reproduce locally?

I can't appear to reproduce it locally on my machine using the urlchecker python module, but I can reproduce it in github CI, which makes me suspect some sites may be blocking something related to the GH environment

That’s what I suspect as well.
