OwnTracks Issue

I have the OwnTracks app installed along with the necessary device. When I paste the given link into my browser, it returnes the expected message: "This is the right url . . . . . ". I have copied that url into the OwnTrack app on my android phone. But when I try to send a report from the phone to HE the logs report a "404" error.

It's probably a simple and dumb error but I have reached the point where I need help.

Thanks
