Firebase-ios-sdk: [!] Error installing nanopb - 503 Service Unavailable

[GuilhermeMachado]

Xcode version: 8.3.3
Firebase SDK version: 4.0.4
Firebase Product: FirebaseCore (4.0.4)

The problem

Firebase core has the nanopb as dependency. When i run pod install command can not clone the repository because it is offline.

I try with the most actually version of cocoapods (beta3) and 1.2.1 version.

Steps to reproduce:

run pod repo update
run pod install

Also to add if you run pod update

[GuilhermeMachado]

I already did that to. The big problem is the nanopd repository is offline.

We're working on the issue and hope to have a solution later today. In the meantime, a workaround would be back-revving to Firebase 4.0.3

No I meant to add as another step to reproduce, sorry to confuse.

The issue has been addressed with https://github.com/google/nanopb-podspec/commit/d7efa2f0e735c57193a78e0552dd61638b2bbbe2, the nanopb pod should be now available.
