Error when trying to update with IPSW

Ok. I think I might be the only person to have this error:

let me translate: Cannot instal software because software update server isn’t available.

Any ideas???

Edit: This may be related, but still, getting the error: If your Mac says that a software update is required to connect to iPhone or iPad - Apple Support

Do you use Finder or Apple Configurator?
It is possible that the Apple server is receiving a large number of devices updating, which could result in this error.
