<![CDATA[Ethernet connection error (timeout)]]>Hi

gui-o designer installed on Win11home.
Configured TCP/IP connection with the IP address of the PC and port 61000. Server started.

gui-o app installed on the phone.
Configured new ethernet connection to the IP and port above.
Connection device fails with:
Ethernet connection error. (Connection timed out).

Tried adding firewall inbound rule to allow connection.
Same results.
Not sure how to diagnose/proceed.

Thanks,
Denes

Glad you've sorted it out. I will try to reproduce this on my Windows 11 machine. This is a kind of a problem that should be on a FAQ list...

Thank you for the feedback.

Thanks for the response.
No mobile data or Bluetooth here just WiFi on the same network.

I changed the firewall rule to allow the specific program (guiodesigner.exe) using domain & private profiles only and when I retried the connection I got a firewall pop-up asking if I wanted to allow it, so after the obvious reply it worked.

Regards,
Denes

firewall should not be a problem on a local network...

You are connected to the local WiFi on your Android app right (the same local network your PC is connected to)? If you use mobile data, this will not work. Maybe try disabling mobile data and keep only WiFi.

I had the same problem when my Bluetooth was turned on / connected. I don't why yet, but is your Bluetooth active (if you have it) when you are trying to establish Ethernet connection? This is a long-shot, I know...

Best regards,
