It always says, that I'm not connected to the internet and the script breaks at that point. But the container is already running and when I go to it's console I can update manually, ping IPs and hostnames:

add option to continue upon Internet NOT Connected #727

Could this new network check perhaps be the reason the LXC scripts are failing with No Network errors on two separate ProxMox installs but working on a third? Fails with multiple scripts tried (MQTT shown as example below). The two failing are in a 10.10.0.0/16 subnet yet both have full internet connections after the failure. The working site is in a 192.168.1.0/24 subnet.

This is the oldest of the checks "Network Check" all it's doing is a hostname -I looking for a valid IP address.
This is the LXC failing to receive a DHCP assigned IP address.

Found DHCP server rejecting 'randomized' mac prefixes, thanks for the lead. Coffee on me tomorrow, thanks for the scripts.
