(Sorry for the bump, but…)
I finally found a solution!
The error happens if your system has only 127.0.0.1 and its public IPv4 address as ip addresses.
You can fix it by creating a new alias for an interface with a private IP (such as 10.0.0.1).
If you’re using systemd-networkd, adding the lines:
[Address]
Address=10.0.0.1/24
to one of the interfaces defined in /etc/systemd/network/ should be enough to fix the problem.
