Your iPad could not be activated because the activation server cannot be reached. Try connecting your iPad to iTunes to activate it, or try again in a couple minutes.
What iPad model is this and is it a cellular data model?
Sorry, I have nothing.
I have a procedure for older iPad 2 and 3 models, but I do not think this will apply to your iPad Pro,
It might be time to bring your iPad Pro into your nearest, “local” Apple Store for diagnosis, evaluation and potential options.
Best of Luck to You!
If it’s a cellular iPad, this iPhone article applies.
