Some of my research indicates a probability its a Chromium browser bug. Not sure yet, but googling the error shows some similar problems. I have a thread open over at Chromium browser forum, but no reply yet,
I sure appreciate your efforts. Maybe we are both discovering something.
Edit:
I just now received the following from the Chromium support forum. Says basically, it’s a browser bug.
This is Bug #1860830 “Geolocation not working − the Google maps API alwa...” : Bugs : chromium-browser package : Ubuntu , and is also being discussed at Redirecting to Google Groups.
