Samsung TV no longer turns on - error

Configuration

I used to be able to turn on/turn off my Samsung TV (UN55HU8550) and it was successfully setup within devices. I am now getting an error:

When I take a look at the logs I see:

I can’t make sense of what is going on. I’ve tried re-adding the integration and this error pops up each time. Stumped to what is going on. Any help would be appreciated!

Did it recently software update?

What software version is Tv using?

This integration requires TV to be ON when HA reboot to establish connection. I don’t think it will connect without HA rebooting.

I think I have same model so maybe I will check. I use CEC and control TV through roku integration

That’s the only thing I can think of. The software on the TV didn’t update (it’s from 2013 (lol) and hasn’t had updates in years. The only thing is HA version changed over that time.

I just started getting that error in the last few days and I haven’t been tinkering in HA to any deep extent.

What version of ha are you on? There were some bugs and changes lately.
