Trouble connecting iPad as a second screen via sidecar

Hi,

I´m unable to connect iPad as a second screen via sidecar. 

I have reviewed https://support.apple.com/en-us/HT210380 and i am sure I’m ticking all boxes for a requirement for this to work.

MacBook Pro Big Sur 11.5.2

iPad Pro 12.9 4th gen SW 14.7.1

Bluetooth on and connected on both devises.

Same WIFI on both devises. Network reset performed. 

Same apple ID on both devises, Password reset performed. 

Handoff ON switched ON, on both

Both devises are connected via Bluetooth.

When trying to connect iPad via sidecar it only gives this message “Unable to connect to “iPad” The device timed out”

Restarted both devices, I have changed password in apple ID. 

Reset network devices performed.

iPad full reset performed.

If I try to connect iPad via MacBook if will disconnect.

If I connect MacBook via iPad if will not disconnect.

It worked fine on both on WIFI and USB, but neither is working.

Hopeful for an easy solution.

Besr regards,

Baldur O.
