I'm having an issue where after a few days ipv6 stops working and I have to restart the network/or reboot for it to come back up/work again.

This is a serious issue. And this keeps happening to a few more peoples in my circle. Who are using this service.

Experiencing the same issue, service started on 2018-07-09 20:16:44 and failed on 2018-09-18 08:51:05. So happens after 70 days or 1692 hours. This is the second time it happened, first time was also after 70 days. Restarting the service works.

Last few days of dhclient-log:
