IPP Printer fails to connect

Having an OVA image of HA running for almost a year now, but after changing my router, the IPP plugin cannot connect anymore to the printer.

Tried running a traceroute from the Terminal to the printer IP. There it looks like it’s trying to connect from the docker network (172.30.32.1) via my router to the internet, so it looks like there is a routing issue as it should stay within the LAN.

Don’t know how it previously worked, but HA has it’s own static DHCP lease from the router and I can access the HA UI interface without issue. Other devices pushing data to HA are also working file. It’s just devices where HA is trying to pull data from that are not working anymore.

Besides the printer also the envoy has the same issue.

Does anyone have an idea how to get networking fixed?
