Grafana is enabled and i can access the dashboard

I found that it’s blocked by NethSecurity Threat shield IP, when the “vpn datacenter IPs” blocklist is enabled.

[MadPatrick]

I don’t see the VPN datacenter IP in IP shield.

But when i disable the DNS shield it connects

Now added the NS8 subdomain to the whitelist, which seems to work

[mrmarkuz (Markus Neuberger)]

It should be listed:

@MadPatrick

Now added the NS8 subdomain tonthe whitelist which seems to work

I think you should add the stats.grafana.org domain instead.

[MadPatrick]

found the VPN indeed. Looking on you mobile not always easy…
This was disabled in my config.

The DNS filter was the root cause.
Added stats.grafana.org

IMHO this is just another example of the utter failing of computing technology in that so much time is wasted addressing a symptom of a completely non-essential function. More than a few of us here have chased this storage wasting “alert”. I believe that at most, more than one notification per day is more than sufficient, not 2 a minute.
