IIRC, that was over a year ago near Oberstdorf, at the border between Austria and Germany. You could not get an on-foot route from the Kanzelwand Bergstation[1] to Fellhorn[2]. The hiking path follows the border closely, crossing it multiple times. That location seems to work fine now.

I’ll make sure to report it in the future!
