Inner exception: 401 insufficient permissions

I have LG C5 OLED firmware: 33.20.60
Everything worked fine for few months, but this week i reinstalled windows11 and updated TV to 33.20.60 after that installed CC again. Most of the functions work fine like Remote control, Game Bar and expert options, but not the power options like "Power off when locking the pc".
This is what log shows when click on "Test power on/off":

Tried different options like "Network IP control" on or off. Mobile TV On and can power on/off TV from smartphone. Quick Start+ is also on. If i'm using unsecure connection it shows:
2025-07-04 12:02:29.8371|ERROR|LgTv.LgTvApiCoreCws|Connect to ws://192.168.88.237:3000/: Unable to connect to the remote server

Any idea how to fix it?

Figured this line var info = await _lgTvApi.GetSystemInfo("modelName"); triggers "401 insufficient permissions" error. So commenting it and next if statement solved error for me.
Only problem - when PC is locked pressing keyboard or moving mouse doesnt wakeup TV. Have to unlock it with black screen to turn it back again.
