Cannot access HomeAssistant from Fedora

Ask Fedora

This is a weird one.
I cannot access my HomeAssistant project from fedora locally or remotely. I am trying to access it via IP address 192.168.##.##:8123 but it comes back with error empty page. I try via Cloudflare using my domain name and nothing. I can ping the machine successfully.
No problems accessing Home Assistant from windows Edge, Brave and Firefox, and my phone. I tried using Brave, Firefox and Mullvad browsers on Fedora. I cleared the cache and even re-installed.
I can access my Synology NAS via local IP no problem. I can even RDP (via Rammina) into another windows box.
Yes, I made sure the port was open.

Something is blocking that particular local address.
Any thoughts?

The specific “error empty page” matters here I think. Are you getting a “can’t connect” or are you getting something else?

Other information that might help is to run (from a terminal) the following commands and share the output with us (replace with your actual IP):

ping 192.168.##.##
nc -v 192.168.##.## 8123

And; fill in the correct protocol here as well (http, or https):

curl -v https://192.168.##.##:8123/

The entire 192.168.0.0 subnet is not internet routable. If you are meaning remote as in from the internet, then you would need to set up port forwarding on your router and access it remotely using the internet IP of the router. This is assuming that you have an internet facing IP and not hidden behind another non-routeable subnet used by your ISP.

Locally within your own LAN that address should work as long as the port is not being blocked by your firewall (on the fedora host) and the app is listening on that port.

Just to be abundantly clear, “your firewall” means the one provided by Fedora.

Thanks everyone. I figured it out. My subnet mask was incorrect on my Home Assistant device. That is why only that one device had issues for me to access.
Cheers!
