LXD works very well on several different bare metal servers, at different hosting companies, but from time to time, after about 20 days, one of the servers looses all ipV4 addresses of all it’s containers.
I don’t know why and I have no other solution than to reboot.
I tried to remove ipV6 for possible conflicts but it does not change anything :
lxc network set lxdbr0 ipv6.address none
All the servers have about the same defaut install config like this :
lsb_release -a
No LSB modules are available.

Is it possible to change something to have a stable configuration?
Thanks
