i have downloaded Frigate from HACS, and can see frigate from integration menu. frigate is running as a docker on my hose, HA is running as a VM.
I could access [frigate IP]:5000 and can access via API on a browser
but if i add [frigate IP]:5000 to the frigate integration, it prompt failed to connect.
im getting stuck and running around like a headless chicken, and if you guys could get me some advice to where to go from here for trouble shooting would be amazing 
Is the VM network configured to let HomeAssistant talk to Frigate?
Hint: Check your IP addresses.
Addons are docker containers
Use host or container name which is documented
EDIT
Sorry docker.
Try ping frigate docker container from HA and verify they can connect
Isn’t there a frigate addon. If running HAOS why not use that for simplicity. Why seperate docker.
sorry that i confused you guys a little bit, I ran HA inside Unraid as a VM (192.168.66.5), the Frigate are setup via Docker in side Unraid (192.168.66.4),
i can access frigate via 192.168.66.4:8971
i can ping 192.168.66.4 within HA’s terminal
how can i verify if HA have access to 192.168.66.4:5000??
Better info on frigate here
My guess is to verify 5000 exposed by docker container. If it is I would expect things to just work in this scenario
5000 is exposed by the container but HA is not playing balls when i try to add the integration…and im stuck troubleshooting.
i have no idea why, but when HA connect to Frigate via port 5000 it has time out error, i am running out of ideas and end up reinstalling frigate, and it works…issue is gone but i have no clue…
better to ask at frigate forum
