Hi all,
Im getting this error Failed to connect: org.bluez.Error.Failed br-connection-create-socket whenever i wanted to connect my newly bought bluetooth keyboard (MAC ID: E4:E8:00:06:BF:AA) on my Raspberry PI 5. I did the apt-get update and upgrade. Nothing seems to fix it.i check the device on bluetoothctl its there. I got it trusted as well. Still couldnt able to figure out what is wrong. Really clueless.. Please help.

root@raspberrypi5:~# uname -a
Linux raspberrypi5 6.6.31+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.6.31-1+rpt1 (2024-05-29) aarch64 GNU/Linux

Code:
