[BUG] Connection refused by server

[servebeer]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Currently, I f I pxeboot a system on the same subnet as NetBootXYZ, I see this:

This used to work, but I haven't tried in awhile. It appears that the DHCP settings are correct. I then installed a TFTP client on a different system on the same subnet and tried to connect the IP address of netbootxyz at port 69, and I get this error:

Connection attempt failed with "ECONNREFUSED - Connection refused by server".
Error: Could not connect to server

Is there a setting in netbootxyz that specifically allows certain IP addresses to connect?

Expected Behavior

I should be able to pxe boot a system, on the same subnet as the netbootxyz docker image, and get to the NetBootXYZ install menu.

Used the Unraid App Store image is not good enough. We want the docker run command.

[servebeer]

Not exactly sure if there is a way to pull that from Unraid. Here are screenshots of the configuration screen that I assume are used when starting the image:

I think something might have changed in a recent update, as I have never seen these errors before:

Just found the Docker Run command:

Are you trying to use a VM on unraid to boot from netboot?

[servebeer]

@j0nnymoe yes, I just fixed the issue. I mannually created the server-info dirctory and favicon.ico file. That in itself did not fix the issue. I then had to change the boot file from netboot.xyz.efi to netboot.xyz.kpxe. The efi file worked before when everything was fine (I don't use this very often, so it has been a couple of months since I tried to use it). Anyway... it appears that it is working fine now, thanks!
