PiHole limiting network access

Hello, i'm not a proxmox or linux expert, so forgive the question if it is too simple. I have a proxmox machine running 6.4-15, and wanted to upgrade to ver 7. In doing so i had to shut down all VM's. One of these VM's is pihole for my network, which is working fine for the clients on the network if their DNS is set to use pihole.
However, no where within any of the VM's do i have pihole set as their DNS. All of the VM's use the router DNS directly.
However, if i shut down the pihole container, none of the other VM's or containers have a network connection any longer. If i start up pihole again, the other VM/containers have a network connection again.
But, in order to update proxmox i need to shut down all VM/containers, including pihole. But then i don't have a network connection any longer and cannot update proxmox because i no longer have a network connection within the PVE.
Can someone tell me what i'm obviously missing or doing wrong? Is Pihole really limiting the PVE network access?
 
Did you set your pi hole as gateway address?

If yes, set the gateway to your routers IP instead of the piholes.
You can see your route with ip r
and in /etc/network/interfaces

DNS configuration is in /etc/resolv.conf

If no, could you add more information about your network configuration? pihole could still be somewhere in your configuration.

Thanks! it was in the etc/resolv.conf file set to the pihole DNS. But, i wonder why? I don't recall doing that. I've set it back to the router as DNS and all works. Thanks again.
