issue with screen mirroring function

[l0neli_m0nki]

My z5 premium cant screen mirror to my bravia today , my phone and TV just showing preparing and after minutes the TV shows nothing the phone gives me the notification saying that 'screen mirroring session disconnect'  , it worked well today before . I can confirm that theres no problem with my TV for I can screen mirror with my another phone .

And I am disappointed to see the HDCP error comes out from the original Z device to the latest Z5 devices .

I'm not really going to be able to advise. 

@uliwooly any suggestions?

Have you also tried to update the firmware in your TV? Some TV-models needs a firmware update to work with screen mirroring and a phone using Lollipop.

sorry for such a long time to come back , yesterday  I tried to screen mirror to a WIDI supported device , I can screen mirror the stock video app and music app content to the widi device , but when I launched any 3rd-party apps , the screen mirror connection turned off and the z5p  telling me that "the output device does not support HDCP........."

Did you try my suggestion about updating the firmware in your Bravia TV?

Are you sure that the WIDI device you tested with supports HDCP?

Also note that if you have unlocked the phones bootloader this will cause HDCP to not work.
