Happened directly at startup:

Sep 08 10:05:46 elsa systemd[1]: cpthook.service: Failed with result 'exit-code'.

Config for reference:

http:
    listen: ":8086"

irc:
    host: "irc.hackint.eu"
    port: 6697
    ssl:
        enabled: true
        cafile: "/etc/ssl/certs/hackint.crt"
    nickname: "ffda-prom"

modules:
    status:
        enabled: false
    prometheus:
        enabled: true
        channel: "#ffda-mon"
        hostname_filter: "(\\w*)\\.darmstadt.freifunk.net:\\d{4}"
    gitlab:
        enabled: false

So likely it's in the irc or prometheus module.
