Found 127.0.0.1. Got the coordinates from the post metadata using ****tool and looked that up on Maps to get decimal format, when I enter the coordinates I get “none was found at that location” so I’m pretty sure I’ve got the right format for the key.
I’ve tried the process of looking up the decimal coordinates and submitting both in Firefox and Chromium, just in case. I’ve tried alternative tools to extract the coordinates.
Unless I’m looking for a different location, I assume there’s some sort of error (rounding in the GPS extraction/conversion?) at play.
