good morning from germany. please post all your settings first.
When you wrote "container" then you mean a LXC an a Proxmox PVE?
please post all your settings.
Mostly you set the wrong default gateway and/ or nor 1st DNS Serveraddress.
 
You either can take screenshots and post them here or you open your cli and past the output of /etc/pve/lxc/<lxcid>.conf in a CODE-tag

Best

yes a lxc container on my pve node
 
So you can $ ping 1.1 ?
You can solve $ dig one.one ?
You have only one IP, that you can use?
You setup 10.69.83.2 for you LXC on PVE, do you have a valid ip, that will route back to you (Proxmox VE Host)?
 
otherwise you will need a only local network on vmbr2, that must NAT to the outer world.
You have to setup real DNS server and/ or dhcpd for vmbr2.
You can't access the vmbr2 from the outer world direct, so you must open and route one or more ports from 10.69.83.174 to you IPs on vmbr2.
