DNS Name not working

When I connect to the IP address Sonaar is bound to (e.g. http://10.10.10.1:8989) it works fine. If I use a DNS name that maps to that ip (e.g. sonarr.local:8989) it fails… Any ideas? Note that this instance is bound to that address and not 0.0.0.0

Bound via Bind Address in Sonarr?

Which OS?

Yes. BindAddress in XML config file. OS is Ubuntu.
Connecting from PC on network. IP works, Name does not. name resolves correctly…

I suspect its due to how that binding works, which validates the request address, not just a restriction on which IP its bound to. We’ll have to investigate:
