WebUI not reachable from any Windows 10 VM

[JonDaniel]

I'm not sure if anyone else has had this issue, but i cannot access the Duet Maestro WebUI from any browser window on any Windows 10 VM. (tested on 2). }

I've been speaking with those much smarter than me over at the Unraid forums, but wanted to see if i'm missing something from the duet config side.

In short, does anyone know why my WebUI would be reachable by any and all devices except virtual machines? (and how to solve it)

Any direction is really appreciated!

Are you trying to reach the IP address directly?
Is your VM and Duet within the same subnet?

@jondaniel do the browsers work with public websites? Have you had success with VMs with a different OS? What url are you trying to use, the mdns .local one? Or the IP?

[JonDaniel]

@phaedrux @gnydick Thanks for replying. I'm trying to reach the ip address directly.

-The ip address of the 3D printer is 192.168.0.10
-The ip address of the VM in question is 192.168.0.47

The VM can successfully browse any other public websites, and can also access several other local docker Web interfaces.

I only have windows 10 VMs right now, but have tried accessing the printer through my iPhone, iPad, Macbook, generic android tablet, and a windows 10 laptop. All were able to connect to 192.168.0.10 successfully.

I have 2 windows 10 VMs, and both were unsuccessful in connecting. I do not have any non-windows VMs to test.

Someone on the Unraid forum suggested i look into manual DNS settings on the board, but i didn't have any luck with changing the network settings (M552, 553, 554)

@jondaniel

Are both the printer and the VM on the same subnet?

@jondaniel have you tried explicitly using a http:// prefix in front of the IP address? I have known browsers try to use https and not fall back to http.

Are you able to ping the Duet IP address from the VM?

[JonDaniel]

@fcwilt yes.

[JonDaniel]

@dc42 Yes, i've tried explicitly using the "http://" prefix.

The strange part is that yes, i can successfully ping the duet ip address from the VM.

[dc42]

@jondaniel my guess is that it's some sort of routing issue, i.e. the VMM is routing the request to the router instead of to the LAN. You could try running Wireshark on the machine that hosts the VMM.

[gnydick]

@jondaniel ok, something interest here. You mention Docker and VMs. Seems like a mix here.

I'm happy to Skype, zoom, etc, if you want some help, I do this sort of thing for a living.

[JonDaniel]

@gnydick that sounds great! I've sent you a DM so we can arrange something.
