Occasionally I will be unable to load the feedback.vrchat.com website with the following error:

I haven't been able to identify any consistencies with when or why it occurs, but the issue will typically resolve itself after a few minutes. This has happened multiple times over the span of multiple months, potentially longer. I don't recall if this has happened on other VRChat domains, but it has happened across multiple devices on my local network. Notably, I do have a Pi-Hole running with the default lists, but I don't believe DNS resolution would cause this.

Quick addendum: I actually had this happen again while writing this bug report lol
