Frigate cannot access IPv6 hosts

[davidebeatrici]

The network interface inside the container only has an IPv4 address:

# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
23: eth0@if24: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default 
    link/ether 02:42:ac:1e:21:01 brd ff:ff:ff:ff:ff:ff link-netnsid 0
    inet 172.30.33.1/23 brd 172.30.33.255 scope global eth0
       valid_lft forever preferred_lft forever
