Setting vmbr0 makes me lose ssh access and makes my VPNs stop working.

[Moofies]

My current /etc/network/interfaces file is:
auto lo
iface lo inet loopback

auto enp5s0
iface enp5s0 inet static
address 192.168.86.204
netmask 255.255.255.0
gateway 192.168.86.1

auto wlp4s0
iface wlp4s0 inet manual
source /etc/network/interfaces.d/*

but I want to setup a container for a minecraft server, so I decided to set up vmbr0.

To do this I changed my /etc/network/interfaces file to:

auto lo
iface lo inet loopback

auto enp5s0
iface enp5s0 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.86.204
netmask 255.255.255.0
gateway 192.168.86.1
bridge_ports enp5s0
bridge_stp off
bridge_fd 0
bridge_maxwait 0


but after doing this and sudo systemctl restart networking, I lose ssh access and my openVPN connection to my server stops working.

Is there something I am doing wrong?
