Proxmox can't ping gateway

I recently purchased a Dell R720 rack server. I loaded proxmox and started moving some of my VM's to the new machine. I tried to check for updates for proxmox and could not reach the update server. Through some newbie trouble shooting I found that I can’t ping my gateway or the internet from the proxmox shell, but I can from the VM. After searching and trying to do what trouble shooting I can, I got frustrated and loaded xcp-ng. I could not ping the gateway or the internet (specifically 1.1.1.1) from the shell. When I look in my Omada network controller, I see the VM registered, but not the host machine. I've tried to set the server up with DHCP then change the address to static and no luck. It will be in there long enough to assign a static IP and in a short period of time, it's gone. My second NIC is assigned a DHCP address and it doesn't show up either. I've reached the end of my trouble shooting skills and I don't have much hair left to pull out.
