Mozilla Deepspeech also uses KenLM language models. What am I doing wrong? If the file formats are incompatible, the failure could be a bit more graceful.

Let me know if you need further info.

Are there any prepared language models that I could try out?

You can download pretrained ones from: http://www.openslr.org/11/

Or more general models: http://www.keithv.com/software/giga/
