No Data for VRN

[marchein]

Since yesterday I no longer receive any data from the VRN backend.

https://dbf.finalrewind.org/Trier%20Hbf?efa=VRN

This is the error the backend provides:
malformed UTF-8 character in JSON string, at character offset 75025 (before "\x{fffd}e / Mutterha...") at /srv/www/db-fakedisplay/local/lib/perl5/Travel/Status/DE/EFA.pm line 39.
