I have the same problem with another firmware and I found a fix for it.
Just have a look if below works for you too.

First step, run you firmware with the debug option ./run.sh -d <brand> <firmware>
Let it run until you reach the debug menu. This might take a while, but you can speed this up by setting the arbitrary option FIRMAE_ETC in firmae.config to false (however, not necessary to make below work).

Netcat will not work because your network is not properly configured, but you can use option 1. connect to socat to access your running firmware and run below commands to check your network configuration.

In my case, there were two issues, first of all the bridge command showed eth2 instead eth0 and br0 did not have any IP configured.
Your configuration might be a bit different. Sometimes you see a brtrunk interface instead of br0.
Anyhow to fix this, run the following commands below and hopefully your firmware will be accessible from the host.

brctl addif br0 eth0

br0		8000.525400123456	yes		eth2

It looks like the target firmware failed on emulation. We need to investigate the system.

@h00die-gr3y
Thank you so much for your investigation, I hope your guide will help the @SaraWonder.
