Unable to screen mirror to my LG TV using my iPhone 15

These past few days I've been unable to mirror to my LG tv (yes it support's it). Used to be able just to open Disney+ and a notification would appear, now every time I try it says "unable to connect". Not only when trying directly from the Disney app but directly from the screen mirror shortcut.

I'm connected to the same wifi on both devices.

Even weirder that the shortcut to turn off or on the TV itself directly from my iphone works fine. Also the remote app works as well but it's impossible to mirror. I've restarted the wifi, deleted the wifi and reconnected on both devices and still not working.

Help please 🙂

I have an iphone 15
