HI everyone,
I am writing because I need some help investigating some errors i've been having this morning.
My home setup is made by two raspberries running OMV:
1) Raspberry Pi 3 runs OMV and Pihole via docker (IP 192.168.178.120)
2) Raspberry Pi 4 runs OMV and acts as main file server and several other docker containers (IP 192.168.178.100)
I have configured my router to use the Pi3 as default DNS server for the whole network:
- IP 192.168.178.120
- domain: fritz.box
If the Pi3 running pihole is up and running, everything works smooth.
On the Pi4 I have set the hostname and the search domain, and used DHCP.
As soon as the Pi3-pihole is down (reboot, disconnects, fails etc.) the OMV web interfaces ceases to work correctly, even by accessing it directly with the IP and not hostname+domain.
It takes ages to load and eventually will simply default with a dialog "An Error occurred"
From the syslog I can see that nginx is restarted several times:

Is there anything I can do to diagnose further?
Thanks!
