Hi,
I running Home Assistant OS10.2 and did a reinstall following this guide. I currently have zero add-ons, it’s a clean install which with nothing added.
I’ll try removing the zeroconf from the config and report back.
I’ve disabled UPNP on my Draytek Vigor2925 and everything is working as it should (except for the UPNP).
Now I just need to restore the system.
Thank you both!
