Frigate NVR “Failed to Connect” Error

So, I’m another person trying to get Frigate to run in Home Assistant. I seem to have have run into a problem similar to others where I get a “Failed to Connect” message when installing the integration. I’ve been doing a bit of searching and have not been able to find a solution so far. I’m running HassOS on an N100 mini pc. Frigate is running internally as an add-on

I have Frigate up and functional. I can see the stream for the (1) camera I have set up for now

MQTT is configured and I’m seeing Frigate when I look in MQTT Explorer

I still end up with the dreaded “Failed to connect” error

Most solutions I’ve found involve using the correct url “http://ccab4aaf-frigate:5000” or “http://ccab4aaf-frigate-fa:5000” but as you can see, ccab4aaf-frigate is my correct hostname and still gives me an error.

What am I doing wrong? I’m going a bit crazy here.

my addon info

My log and config in case it helps

Thank you. I had tried both and neither work.

I’m very puzzled.
