A third party service is sending me web hooks, and they are seeing a 403 response code. Unfortunately, I’m 95% sure that’s not coming from my app, which means it’s coming from somewhere in the following stack:
Provider → Cloudflare → Render → Rails App
Interestingly, it no longer 404s if I disable SSL for that web hook endpoint, but that’s not a solution I want to go with long term.
Everything I can see on Cloudflare’s docs would suggest they never return a 403 (although the fact that disabling SSL solves the problem makes me suspicious!)
I’m wondering if there’s any way for me to see requests hitting the render router/load balancer/whatever for my app so that I can rule that out?
