Hello, I'm very new to HA. I would love some help troubleshooting an issue I'm having.
I have successfully added Kasa smart plugs to HA using TP-Link Smart Home integration. I recently bought smart bulbs that are matter compatible, but I'm having trouble adding matter integration to HA. The error I currently get is "Failed to connect" see the attached screenshot. Home Assistant is running in Docker on my Ugreen NAS. I didn't have this issue when adding TP-Link Smart Home integration. I asked Gemini and the AI thought it was an issue with the URL. It asked me to turn off the automatic setting fro the internal URL in my HA settings. However, the URL in this box was already correct when I wen to the settings page (correct IP and port). I also tried hard-coding the internal URL in the YAML configuration file, which also didn't solve the problem. Happy to provide any additional details or logs to diagnose this problem.

Do you have a matter server running?

The recommended way of using matter with home assistant is to use the matter server add-on via HAOS. getting it set up with docker can be challenging. would it be possible for you to switch to using HAOS, for example in a virtual machine?

It's not particularly difficult getting it up and running with an HA Container installation (I have it running on my end)
