Dear community.
After buying a house with Loxone smart home installed 2 years ago, I have finally started to want to add some extra functionality to it.
I have bought an RPI 4 and installed the latest loxberry on it.
I want to try the following plugins: Docker (for Unifi controller), Nibe uplink (for some status values for our heating system), and Sureflap (for integrating our cat flap into Loxone).
I have installed all 3 plugins but I cannot get either to work.
Docker:
I'm following
this tutorial for the installation of Unifi controller. When I try to deploy the container I get "Failure, no such image"

Nibe uplink:
When I try to authorize the application I get the following error after confirming the captcha.
Sureflap connect:
I get "Curl Failed".
The logfile shows me:
sending not encrypted in http-Mode
Getting last token
Starting request...
Request received with code: 0
WARNING: Token needs to be renewed!
Requesting new token
However, if I use an API tester (e.g.
postman.co), it works just fine. So I believe that the problem is in Loxberry trying to call the API.
One general comment that could be connected to all this is that I also get the following error when trying to install new plugins.
We are in CGI mode.

If I press the link, it will download. So It seems like Loxberry can't reach the internet.
Unfurtuanly it seems like most Loxone users in the world are German-speaking and that 99% of Loxberry documentation is in german. I have tried translating most of the information there, but neither of the information has helped me.
If anyone can help me with this I would be very grateful.
Thanks
