Home assistant blocked on network PC

Home Assistant is installed on my Server 2012 R2 and can be accessed directly on that PC. It can also be accessed by remote connection over the internet from other PCs. However, it cannot be accessed using either of my win 7 or win 10 PCs which are connected by ethernet on the same network as the server. When I enter 192.168.1.xxx:8123, the web page stays blank for a few minutes, then the following appears:

This site can’t be reached

192.168.1.xxx took too long to respond.

All three PCs have Windows Firewall active and additional apps can be allowed to communicate. However I do not know what to specify for the Home Assistant app. It is installed under Python/----------/Sire Packages/ Homeassistant.

What is the best way to get access to Home Assistant from my networked PCs?

Just unblock TCP:8123

Did you install fail2ban on the Pi with HA on? I started getting this when I was messing about and failed to log in 3 times in a row.

No, I did not install fail2ban. I had to look it up just now to understand what it is.

Sorry, just read your original post again and realised you’re not running this on a Pi.

So I did unblock TCP:8123, but still cannot access Home Assistant from my networked PC.

Do the logs show it actually starting up properly?

I had to redo the port opening and now I can get to the login and it accepts my credentials but it fails to connect to Home Assistant. If I log in using the server or by remote connection to the server, it goes directly to the interface. Is there something else that is blocking access to the interface when logging in from the network PC?

You get a login prompt, which succeeds and then you what get a connection timeout?

Yes. The Chrome page shows the Home Assistant logo on a white background and
Unable to connect to Home Assistant.
RETRY.

Retrying only produces the same result.

This only happens when trying to connect to Home Assistant which is installed on my server from either of my PCs. connected to the same server by ethernet.

Does disabling the Windows firewall fix it?

Turning off the Windows fire does not fix it.

How do I check the logs?

Actually it must be starting up properly because it works fine from the server or via remote connection on my two networked PCs.

We had a power failure and when power returned. I successfully logged into Home Assistant and am now configuring.

Who Knew? LOL!!
