Fritzbox collectd issue InfluxDB Error: database not found: collectd about synology-fritzbox-grafana HOT 1 CLOSED

I think I found the error myself.
In my opinion, it's about which characters you use in the password.

For analysis purposes:
I proceeded as follows:

• Searched out the corresponding Docker via Portainer.io and connected to the console.
• Then execute the command "fritzstatus". Here you get the message for further information a user and password are to be named, so I noticed that my password was not accepted.
• Password changed in the fritzboxcollectd.conf changed
• Restarted the system, reconnected to the console and checked whether the password worked.
• After a while (data was collected) Grafana shows all values in the Fritzbox overview.
