NMEA Decoder on AIS-catcher.org not working

[flygfantast]

When trying to use the NMEA decoder on the page it returns:

"Decoding Failed
Error: Network error: Failed to execute 'text' on 'Response': body stream already read. Check browser console for details."

Failed to load resource: the server responded with a status of 403 ()
API response status: 403
