Hi Guys,
My issue is: when i "Build and Run" my project from Xcode to my iPhone, i see in log this type of error:

2017-08-01 01:44:00.868946+0430 GameName[3540:934225] [Firebase/InstanceID][I-IID003009] Failed to fetch default token Error Domain=com.firebase.iid Code=0 "(null)"

i do all things step by step from web site, and all of my plugins and applications are updated.
i use firebase analytics and adMob.

hi, i was facing this problem too, in IRAN, thanks to all google... we are blocked ... i was facing this problem about 5 days and try every tutorial in net... but nothing solve my problem, Domain=com.firebase.iid not responds and it doesnt give me a token... but when i connect to a VPN then connection between device and iid.firebase.com domain established and token generated, try connecting to VPN and check again.

Yeah, Thanks Farshad, it was not a real problem, i done it a day after i post this question, but its too crazy, because i couldn't debug any problem in such these cases... thanks again for your answer and your time to solve it.

I tried much time but only with VPN we can connect to FCM ...
