Problems with activiting allow "emedding"

Grafana Configuration
1

Dear community,

I need your support, to be honest, I don’t know that well. Also with Linux i am not so conform.

my Setup:

  • QNAP
  • Grafana (Grafana v11.5.2) installed on a container there

I want to show some Grafana dasboards in my iobroker. For that i need to activate “allow_embedding”

Via SSH i logon to the QNAP and change the grafana.ini via nano:

docker exec -it grafana /bin/sh
cd /etc/grafana/
ls -l grafana.ini  -> -rwxrwxrwx
nano grafana.ini

I changed there the value “allow_embedding = true” and saved

If i open the grafana.ini again, i can see the changes to “true”. So good so far.
Now i stopped the docker and start the docker again (also i tested with a total restart of the QNAP.

If i check with SSH again, i can see its still “true”.
But if i go to the grafana website to settings i can see its “false”.
