New installation-image not connecting to internet, message Ipv6: eth01: Ipv6 duplicate address

I lost the connection to my hassio version 0.93.2. on my raspberry PI 3
Flashed a new sd-card, and started it up.

Now it is not connecting to internet, and I get message IPv6: eth01: IPv6 duplicate address on [3 addresses].

I have tried two different pi’s and different sd-card, so it does not seem to be hardware.

IPv6 is diabled on my router.
Do anybody have an idea what this might be?

Any ideas?

(For anyone with similar issues…)
The problem was a network issue. No errors on the hassio or the PI.
