ERR_NETWORK_CHANGED on Chrome with Ubuntu 17.04

For anyone else that probably didn't think of it like me - this was being caused by a docker container I had running on the machine.

Making a js request while starting a docker container seems to trigger this kind of error. Somehow connected with the docker network, when containers are dynamically added/removed. Chromium only, not seen on Firefox.

This still happens in Ubuntu 18.04 and Google Chrome Stable (80.0.3987.106 now).

Disabling Docker reduces (not eliminate) this issue, and using sysctl to disable use_tempaddr also reduces too (still didn't eliminate).

I need to totally disable IPv6 to avoid this issue, by changing /etc/default/grub from:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To:

GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 quiet splash"

Then running Docker would be fine.
