You can reproduce that finding directly from python:
```
>>> request.urlopen("https://anc.dev")
[...traceback info...]
urllib.error.HTTPError: HTTP Error 403: Forbidden
```
In this case (https://agents.withgauge.com/p/runs/40be763c-4678-4677-88df-...) the agent wrote a python script to test the site, and hit the error above. We don't have a full filesystem diff viewer in ax-check.com, although we do have that in the Gauge agents product itself.
Interesting, thank you. I'll check whether a setting on CF might be interfering. The site checks headers for routing and response types, but it shouldn't affect access.
