MMM-GrafanaCharts page not found with Grafana 8.0.6

[Babene1]

i want to use the MMM-GrafanaCharts in my MM but page not found.
I have grafana 8.0.6.
I have no idea where the error could be. I would be very grateful for a hint.

in normal Brpwser the page works, here is the ULR

Here is my module config

{
			module: 'MMM-GrafanaChart',
				position: 'top_right',   // This can be any of the regions.
				config: {
					   version: "8", 
					   id: "QG8S2mWnk", 
					   host: "192.168.178.248", 
					   port: 3000, 
					   dashboardname: "raspberryklein", 
					   orgId: 1, 
					   panelId: 2, 
					   width: "500px", 
					   height: "500px", 
					   refreshInterval: 900 
				   }
		   },

@babene1 where is that host?

@Babene1

Your config looks okay to me.

I do not use it anymore, but from my notes (June 2020):

$ sudo vi /etc/grafana/grafana.ini

[auth.anonymous]
l
# enable anonymous access
enabled = true 

# specify organization name that should be used for unauthenticated users
org_name = MagicMirror

# specify role for unauthenticated users
org_role = Viewer

[security]
# https://grafana.com/docs/grafana/latest/installation/configuration/#allow-embedding
allow_embedding = true

$ sudo systemctl restart grafana-server

I cannot remember why I needed this.
Perhaps because of the allow_embedding and enabled settings.

Good luck,

E.J.

i found the problem, in my case the “panelId” was the problem.
I don’t know if the problem only occurs in Version 8 from graval or if an configuration misstake in my grafan evironments.
I delete in MMM-GrafanCharts.js files the panelId in the iframe.src URL and now it works
