NextDNS cli: Error: service nextdns start: exit status 1:

Hi,

I'm trying to set up NextDNS to run on a docker container on a Synology NAS. Tried setting it up from scratch based on Debian and even some existing image (terafin/nextdns-proxy). It worked once while testing things but it never worked again, and I always get the same error ("service nextdns start: exit status 1:").

Tried recreating everything from scratch, checking network, restarting, etc. But I always get the same result. Since the error message itself seems to be broken as well, I'm not sure where to start troubleshooting.

Any help, please? :)

Even if I try to get a status I'll get the same error:
