Yes it worked but it shouldn't be like this, something is wrong. After changing the IP it seems to me that the 29810 UDP port disappears in docker and it is probably responsible for adapting devices.

Regardless of the controller version, whether it is a stable or beta version, it is always the same. Did TP-Link mess something up in the software or maybe block the ability to install controllers on the raspberry pi 4???

I have installed the latest beta version 5.15.20.12 on Ubuntu 20.04 server and on Raspberry Pi 4 and 5 with Raspberry PI OS lite without any problems, there were a few problems the first time because I had to upgrade the java version but once that was done it worked fine. so you were probably just unlucky. but it's good you got it working.
