After Hassio 0.89.0 update duckdns login not working anymore


After updating to version 0.89.0 I am not able to acces home assistant with my duckdns domain.
Running HassOS 2.10 on a Rpi3b with NginX addon.
It is only possible to acces hassio with hassio.local:8123 and with mylocalip:8123
There is nothing about this in the release notes.
Is anybody else experiencing the same issue?

Thanks in advance.


Running HassOs in a VirtualBox VM I was able to access through duckdns after upgrade to 0.89.


PROBLEM SOLVED --> Port forwarding was missing somehow…
