Vaultwarden dont Start on Yunohost

Hello

i install Vaultwarden on Yunohost (Respberry Pi 4) when i start App the failed with this Code :

 vaultwarden.service - vaultwarden Server (Rust Edition)
   Loaded: loaded (/etc/systemd/system/vaultwarden.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Fri 2022-01-28 09:04:21 GMT; 15min ago
     Docs: https://github.com/dani-garcia/vaultwarden
  Process: 23355 ExecStart=/var/www/vaultwarden/live/vaultwarden (code=exited, status=1/FAILURE)
 Main PID: 23355 (code=exited, status=1/FAILURE)

and when i open it with localIP/vaultwarden the message is

502 Bad Gateway

nginx

What are the Problem here ? i cant find anything.

I guess it’s not started at all since i see a failure message.
I suggest to check the logs, or start it manually and see what happens.
