BUG on MAJ, i canno't do this

Hello, since Saturday 14/12/2019, heroes of the storm asks me for an update that I can not do.
I have the message: oops! What a horror, a mistake: Try again.
Advanced aid: BLZBNTAGT00000BB88

I tried again, with and without computer protection, nothing helps. Before, I had an identification of my authenticator following my registration for Diablo 4.
Is that due to that?

So, even the update 49.1, I can not do it, suddenly, I am unable to play a few games to relax.

Thank you for bringing this back to my side.
