[Burak Malkoc]

Upgraded the firebase-messaging integration from 17.3.4 to firebase-bom:26.1.1 with com.google.firebase:firebase-messaging-ktx included. Within the setup token retrieval process is working on a real device however can not retrieve the token on emulator and receiving this error. Any idea how to get this work?

Hi,

You should be able to get a token on an emulator. FCM will use the same services on the emulator as on the physical device so I'd expect it to work. Seems like the emulator is having trouble reaching the Firebase Installations service. Couple things to try:

- Uninstall and reinstall the app on the emulator

- Confirm that the emulator has network connectivity

- Restart the emulator

Even tho I tried the steps above, nothing changed. 
So my current solution is changing emulator dns server to 8.8.8.8

./emulator @Pixel_4_API_30 -dns-server 8.8.8.8

[Arthur Thompson]

Thanks for sharing your solution.

Hi Burak,

It seems strange that the emulator had connectivity but was unable to reach Firebase due to DNS.

Was there some DNS setup on the host machine that prevented the emulator from reaching Firebase?

[Burak Malkoc]

Is there any firebase public ip addresses that I can ping to test out if the problem is really dns based?

[Burak Malkoc]

After couple of restart of the Emulator, changing DNS is not a consistent solution.

[Arthur Thompson]

I see; so even after resetting DNS your emulator is still unable to receive tokens but is able to have other types of network access?

[Burak Malkoc]

Yes indeed.

[Arthur Thompson]

That is really strange, is your emulator able to use any other Firebase services like Auth, RTDB or Firestore? I'm trying to see if this is an FCM specific issue or more general.

Even tho I have started the emulator with DNS 8.8.8.8, when I trigger https://firebase.google.com/  on chrome, I get this cert issue and I can't get the token by seeing this error on app "FirebaseInstanceId: Failed to get FIS auth token" 
Might be related?

[Arthur Thompson]

Hi Burak,

It seems like there may be an issue with reaching Firebase on the whole from your emulator, so this is more a cert issue than an Instance ID or FIS auth token issue. I would suggest trying to get the emulator to reach firebase.google.com then the app's ability to get tokens should also be resolved.

It turns out that, if you have Netskope Client running in your computer, that blocks some google services so results with FIS Auth error. Disabling Netskope works it out.
Thanks for your support

Hi Burak,

Thanks for sharing those findings. I'm sure it will be helpful to others.
