Ipad unavailable - no time countdown

My iPad says "iPad unavailable" and there is no "Erase iPad" option or countdown counter

When I tried to connect it to my computer & iTunes, it does not connect. Other devices are ok.

The iPad does not show "charging" when connected to the computer with the USB either but it is charging.

Any help/suggestions would be appreciated!

It's been like this since Sept, doesn't connect to wifi or show up in 'Find my'.

There is no countdown timer to just reiterate
