Homeassistant stopped working on Synology

In January I managed to install Homeassistant on my Synology ds216play. It worked just fine until this morning. Now I tried to restart it from within the app. It stopped working and I haven’t been able to restart.

I used the Hass-daemon under ssh. The daemon runs fine, but Homeassistant just won’t start. It produces an empty log file. The PID file contains 30140 and nothing else.

I know next to nothing of Linux, so I need help badly!

Thanks!
