Localhost doesn't work in configs


I recently started using Home Assistant. I’ve followed the “official” way of installing HA on an Intel NUC.

I’m having some issues though. No add-on (any add-on) works unless I specifically add the device’s IP ( to the configs. If I use “localhost”, it never works for some reason. Same goes for any databases, Grafana and any other add-on that requires setting up host.

Edit: As an example, when setting up a quick database with InfluxDB and connecting Grafana to it I have to use its IP instead of connecting it to localhost, otherwise it won’t establish a connection to InfluxDB.

Any help is greatly appreciated. Thank you!
