It looks like your OPNsense installation on Proxmox is facing network connectivity issues, preventing it from resolving domain names and reaching update servers. Since you cannot ping 1.1.1.1, the issue likely stems from incorrect gateway, DNS settings, or VLAN misconfiguration. Ensure that your OPNsense has the correct default gateway and DNS settings (e.g., 8.8.8.8 or 1.1.1.1) under System > Settings > General. Also, verify firewall rules and NAT configurations to allow outbound traffic. Since your setup is similar to your production OPNsense, compare the Interfaces > Assignments and VLAN settings to spot differences. If you're running any PHP-based scripts or services on OPNsense, ensure they are not interfering with connectivity, and try manually configuring DNS servers via the command line using chattr -i /etc/resolv.conf before editing.
