Description

Instead of the Web UI address being http://BRIDGE-IP:7125, I found that http://0.0.0.0:7125 worked, based on what was printed in the console when I first ran the executable:

[18:14:41] INFO  bridge: [Drucker 1] Verbinde mit :9883 …
[18:14:43] WARNING bridge: [Drucker 1] Verbindung fehlgeschlagen: [WinError 10061] No connection could be made because the target machine actively refused it – Offline-Modus
[18:14:43] INFO  bridge: [Printer 1] Bridge running on http://0.0.0.0:7125
[18:14:43] INFO  bridge: OrcaSlicer → Klipper → Host: 192.168.2.14  Ports: 7125
[18:14:43] INFO  bridge: Ctrl-C zum Beenden

However, neither http://BRIDGE-IP:7125 or http://0.0.0.0:7125 worked in OrcaSlicer.

Steps to Reproduce

  1. Download and unpack kx-bridge-windows.zip
  2. Run kx-bridge.exe
  3. Navigate to http://0.0.0.0:7125
  4. Add Kobra X printer via IP address
  5. Open OrcaSlicer and add physical machine
  6. Change Host Type and Printer Type to Moonraker
  7. Test http://0.0.0.0:7125 (or http://BRIDGE-IP:7125) in Hostname field

Expected Behavior

KX-Bridge would complete the connection

Actual Behavior

OrcaSlicer gives me this error:

Couldn't connect to Moonraker. curl:Couldn't connect to server. Failed to connect to 0.0.0.0 port 7125: Address not available [Error 7]

Here is the output of kx-bridge.exe:

Based on the kx-bridge.exe console prints, I found that using the hostname http://192.168.2.14:7125 completed the Moonraker connection.
However, it looks like the addresses are all over the place and should be looked at.
But thank you again for developing this great software! =)

Fixed in nightly. The startup log now shows the actual LAN IP instead of 0.0.0.0. The bridge already determined the correct local IP via a UDP socket trick — the log line just was not using it yet. The line you want to copy for OrcaSlicer is now: OrcaSlicer → Klipper → http://<your-ip>:<port>
