[Issue] Error during integration setup: Failed to connect. Check provided settings.

[rapco]

Hi,

I am getting the error "Connection test failed with exception <class 'OSError'> Args: [Errno 113] Host is unreachable" trying to setup my Bambu Lab A1 printer.

I get "Failed to connect. Check provided settings." at Setup Local Connection section

In the Home Assistant logs shows: Connection test failed with exception <class 'OSError'> Args: [Errno 113] Host is unreachable.

The error indicates your home assistant cannot reach your printer. A few more details would help. Are you trying to connect in lan mode or with bambu cloud? Is the IP address pingable from your home assistant?

Yeah! I got a thing in my network that HA is one subnet and all Wifi devices in another.

I was able to get it recognized by enabling peer to peer rounting that creates a havoc in my network. Pretty much making the network flat.

If I did it correctly I set up the Firewall to allow all communication between RM4 Pro and HA but does not detect it. Is there any trick to get it to work from a different sub net?

It depends on your router. The minimal approach is to add an allow route for your home assistant to connect to just the printer IP on just the single 8883 port needed for MQTT. A1/P1 camera will need port 6000. X1 RTSP camera will need one of 322, 554 or 8554 - I'm not sure which these days. Or you could allow your HA to connect to any ports on the printer IP address. Make sure to use fixed IP addresses if you're doing this so it doesn't randomly stop working later.

Closing as this is a networking issue, not a bug.
