firebase init gives EPROTO error - firebase

Question

Running firebase init command gives an EPROTO error. Same error when I try firebase list. I can successfully use firebase login though. Here is the output of the firebase.debug.log:

You're about to initialize a Firebase project in this directory:

[info] First, let's associate this project directory with a Firebase project.

Answer 1

Cause:
Eventually I found that my ISP had updated its so-called Kids Safe security settings and was treating admin.firebase.com as a blocked file sharing site.
Solution:
I updated my settings in the ISPs config, so that access to firebase.com was always allowed. Now firebase init, firebase list etc are working fine.
