I am trying to configure the Toradex Easy Installer to search images using avahi zeroconf. For this, I downloaded the Easy Installer version ToradexEasyInstaller_5.4.0+build.4. I followed the instructions pointed out in Detailed Manual | Toradex Developer Center.
When I start the VNC Viewer and click at the Feeds tab, following dialog gets displayed:
When hitting the OK Button, following error gets displayed (Error downloading image list: Connection refused):
What could be the reason for this issue?
This is the content of the image_list.json file:
emb-sys@ubuntu:~$ cat /var/www/html/image_list.json
{
"config_format": 1,
"images": [
"Tezi_1.0.0-devel-20211005065744+build.0/image.json"
]
}
This is the directory structure:

The host PC is Ubuntu 20.04.3 LTS.
The SOM is running on an custom carrier board, which is inherited from the Colibri Eval Board 3.2B. The processor is a Colibri iMX7D 1GB V1.1A and the OS is based on 5.2.0-devel-202103. The kernel version is 5.4.91-5.2.0-devel+git.c59b3c2da1e9.
One more hint: When setting up a nginx web server as described in Detailed Manual | Toradex Developer Center I am able to see the available images from this web server. So I believe, there is no firewall issue which rejects the requests.
Thanks on any hints you can provide.
