My Home Assistant OS is running on a Raspberry Pi 4, and Agent DVR is installed on Windows 11 Pro. The Windows network is set to private, and the firewall is G Data, where I have opened port 8090. API is not enabled.
The following problem occurs: I go to Device Integration in Home Assistant, try to add Agent DVR, and it asks for Host and Port. The port is clear: 8090.
For the host, I assume it is the IP address of the Windows PC (e.g., 192.168.x.x).
I entered it like this:
I also tried `localhost` and similar things.
**Something is blocking it**, but I cannot figure out what it is.
**A ping from Home Assistant to my PC worked, so the PC is reachable**.
I cannot figure out where the issue lies.
**Do you know more? Maybe a hint would already help.**
