When I use Google Chrome (currently 61, but the error exists before), I constantly get
ERR_NETWORK_CHANGED. Often, the webpage reloads and works a second later, but often things simply don't work. For example, I'm not able to download files from Google Drive at all, because a XHR call fails with this error (this is an example. The error is not specific to Google Drive).
Social logins with Google / Facebook are not possible, because the callback after the login are failing, too. The problem exists in incognito mode, too.
With Firefox, there seem to be no problems.
On Ubuntu 16.04, the problem doesn't exist.
Ethernet controller is a I219-V. Not able to try other machines.
While writing this, I found out that disabling the IPv6 privacy extensions with
sudo sysctl -w net.ipv6.conf.enp0s31f6.use_tempaddr=0
and restarting the interface seem to be a workaround solve the problem, but obviously it's bad to use workarounds instead of solving the root problem.
- Whats going on here? Why does this affect Chrome and not Firefox? What is the difference?
- Whats the difference between Ubuntu 17.04 and 16.04 regarding this problem?
- How can I get more information about the problem?
- Is this a known problem with Ubuntu 17.04?
