What am I doing wrong here? I see no red flags in what you are describing and in the provided logs. Unfortunately, ACLStringData::match() does not log the strings it is comparing the configured ACL value against, and I lack the free time necessary to triage this further for you right now. Hopefully, somebody else will volunteer to triage this. It should not be very difficult to get to the bottom of it.
